Well sorry you take offense to typos, but this is the internet. They're gonna happen (like when you called me CGI quality one time instead of CGI-Quality). Not a big deal.
To the game, everyone who's played the game has said the A.I. is second-to-none [literally]. No game before it is as smart. You basically got the answer you were looking for.
Well, if you remembered it after all this time, then it must have been a big deal. When it comes to usernames, I know how important these things are. They're our trademark. They are who we are. And if you change the username, it's like you're changing a person's character. Y'know?
Aaanyway, yes, the game appears to have some nice AI. I wouldn't say THE best, but still amazing.
