dude, some of you guys need to go use the search feature.. i have explained millions of times why sc is great and its not just balance, the online system of battle.net which was created for starcraft and later lead to wc2 b.net edition along with the diabli and rest of the wc series joining it. the single player campaign which is gripping, teaches you how to play well and has an amazingly well-made story. The balance...ofc...
The maps and custom editors etc. Starcraft pretty much invented custom maps, it was possibly the 1st game ever with "triggers" allowing you to make all sorts of effects. All games before only allowed you to make a map then play it normally. on starcraft people started making maps where you had 1 unit which you could upgrade.. then micro maps were born. soon after that mass attack maps and bound maps were born. The mapping on this game started a whole revolution. I think every wc3 fan will agree without Starcraft DOTA wouldnt exist.
Maps got more and more complex and as new custom unofficial editors like SCM Draft, GU Edit, X-Tra Editor came out it became possible to make units invisible which shouldnt be.. make ramps wider and thinner than normally allowed, make new doodads. Custom maps started copying other well known games and even film maps were introduced. Where scripts were made for charicters and your screen automaticly followed the action.
The sound files allowed in SC let people experiment more with audio instructions and sound effects added to the games.
ok.. yah see now you got me started its tempted to explain the others more

. Ontop of all of that there is the immense popularity of the game.. ok, so it means some people say its good just to be a sheep. But alot of that popularity is true fans like me. In zero hour, age of empires dawn of war no matter what.. you often see no more than a thousand or so people online at a time.. on starcraft there is never a shortage of opponents.
The game also runs on almost any computer... this means people from poorer countrys get a chance to play some pc games. the game will even run without lag on a 28k modem! This game is giving alot of poorer countrys a chance to get a say in gaming aswell.
The Melee games are intense, as mapping progressed Fastest Maps were introduced aswell where minerals were all stacked giving a near endless supply and increasing your income by a huge percentage. This means games totally changed, rushes were faster, bases were bigger, armies were bigger, battles were bigger. Appealing to many people it even started several leagues and tournaments.
Low money maps remained the focal point though. Although many people think korea totally dominate the SC scene they are actually quite incorrect. More koreans play starcraft than the rest of the world put together now. But still countrys like Poland, Germany, Russia, USA, Canada are still all well up there, and the top players from those countrys can often beat some of the famous koreans.
On a lower down level players kept it intresting by creating PGT, WGT, BWCL along with hundreds of other lesser known leagues. This allowed players to play competatively at their own levels. Still PGT and WGT are no place for noobs, but now even i hope to start a new league. Allowing lesser skilled players in and opening it up to the newer players who often feel not good enough by the shire number of skilled players online today.
What shall i explain next? Balance?
The balance on starcraft is the most famous bit. Never before and never since has there been a game where evrything possible has a counter, and its a 3 way thing! Each race has a counter for every unit in every other race.. protoss vs zerg the zerg goes hydras to counter goons... so the protoss goes storms.. so then the zerg goes air.. so the protoss goes corsairs, so the zerg goes devourers and hydras... then the the protoss gets dark archorns for mealstrom and storm... so the serg gets cracklings and defilers.. so the protoss gets reavers and zealots... so then the zerg gets ultralisks.. that is just 1 match up.. the possibilities are truely endless.
if someone went mass battlecruiser (one of the most powerful units in the game) then the protoss could kill it with about 2-3 psyonic storms, which takes less tech and less money.. the zerg could use scourges + hydras or plague + hydras. The same applys for every race.
Infact i just found something to explain the balance even better, i stole this off lollypop i think his name is from another thread on here.

Took me about 20 minutes to copy that from the strategy book. Enjoy..
And now consider how insane it is to start countering the counters, and when you have a selections of several of the units all together. e.g. reavers+corsairs vs zerg..
Micro + Macro
Lets face it.. starcraft invented it really. Prevoisly the RTS genre was full of games more like Total Annihalation and the C&C series, both of which were more focused on building massive armies with an endless limit then oblitterating your enemies with massive numbers. No micro or macro required in comparison to alot of todays games like DoW or Zero Hour.
Macro came in because on starcraft it was alot harder and slower to build up a good econemy. So people wanted to spend every penny wisely. Build orders started being made as it was discovered you could tech really fast or go basic units or do safe builds to protect vs an enemy who did either. Hundreds of stratergys were born. Fast expansions, slow expansions, deffensive expansions, rushing with deffensive buildings, building near/inside the enemys base, going mass deffense and teching to carriers/bcs etc.. massing out on everything and expanding when needed, going unit drops, pushing with tanks, reavers or guardians or lurkers. The list of tactics born is never ending, and everyone came up with their own versions. People soon discovered you could disrupt your enemys Macro skills by harrassing them or stealing their money. The now well known manner pylon was born along with several other simular tactics.
Macro was more or less invented by SC.
To start on Micro is impossible.. i guess one day some1 realised when fighting zerglings with marines that he could move a marine and the zerglighs chased allowing his units to stay alive more easily fireing on the zerglings from range.. then the zergs got burrow and started learning to flank and ambush troops. The protoss started learning effective ways of using their spells such as psyonic storm and d-web. Soon it turned into a frenzy with everyone selecting what their units should attack whilst reatreating others and attacking with another squad in a totally different part of the map. Whilst doing all of this the players had to remember to macro controling their resources and maybe even teching at the same time. Players soon discovered bugs in the game like burrowing a unit under another then unborrowing to get past mineral blacks or anything else.
Players started placing buildings strategicly to help them micro and deffend.
Starcraft invented almost all of this! Without starcraft alot of modern RTS games you guys love wouldnt exist.
now that ive spent half an hour writing this and live in fear of a power cut id like absolutly every one of you who thinks this game isnt the best RTS to explain why what you think is the best RTS is the best RTS.
I have played alot of RTS games as alot of you know. And from what ive played this is the best.
I have probably missed quite afew things, but when i think of them i will add them.
