I've played Halo on the other hand, and there is an FPS that definetly could be an e-sport. Lots of games like CTF involve elements of map control that you see in starcraft.
it is. halo is an esport. if you have halo waypoint on your xbox live (its a free download) then you can whatch some matches. halo is actually a good esport too.
and @ the OP, tell me this: how is it different than this game. its a sixty dollar game you can buy at most game retailers, involves lots of different people, some of which are horrible, others of which are good at it. plus both sides have cheesers and cheap ways of instant wins (tactical nuke, despite the 25 kill streak required, its an instant win.)
its like star craft, just a different type of game. and different types of games cannot be compared, becuase they arent similar enough.
