I know I'm going to regret asking this, but why is BW better than SC2?
And don't just say it's better balanced, go into detail. I'm very curious.
It's not really a question of balance per se. SC2 is quite well balanced. To put it as simply as humanly possible, SC2's multiplayer design craps all over the basic tenets of strategy gaming (most of which reflect qualities of war in the real world in some way), and this makes parts of the game either boring or painfully retarded.
For example, the game lacks any basic mechanical reason to spread your army around the map, instead promoting turtling on three bases, and then attacking with a huge maxed out army. The mobility/power relationship is completely out of whack in SC2, huge armies can cross the entire map in a matter of seconds in many situations, which renders any positional play all but obsolete. Also, the SC2 team has a hardon for unit abilities that make it impossible/difficult to control other units - various slows and stuns and impassable barriers - that go against the basic joy of playing an RTS game: controlling your units to improve their effectiveness. I sometimes fire up Brood War to get owned on Fish, and I always marvel at how fun it is to just micro dragoons around. This also makes retreating extremely costly, which again causes everyone to just sit in their base, massing shit.
If you want me to, I can produce a huge essay on the failings of SC2 Multiplayer, honed by months of arguing with retards on TL.
