Typography? (Answers your...wait, ypou didn't actually ask a question.)
I didn't say I was good, just that I play them. My stunning online record for Warcraft, in the brief time I played, was 0/3.
Besides the normal online games, you can play "custom games" which still use the Warcraft game, but the gameplay is completely changed (in most cases). DOTA is one of the most famous types of Custom Games, though I only played it once, and my team was apparently so inept we lost within the first few minutes. I didn't even have time to figure out was I was supposed to be doing.
Oh, no. You have no idea.l There are games, mainstream games, where the AI would tear all but the godliest of players apart. Perfect Dark is a prime example, with the elite AI opponenets doing things that are almost impossible for a human to do (I use almost because I watched old-school tournament footage of human players putting the elites to shame....WITHOUT the use of cheats.)
