If you ask about Apple OS X games on /v/, you're going to get drowned in trolls. We'd like to apologize for that: sorry.
Damn near every major game made for Microsoft Windows also has an OS X version these days, so check that out until we can get /v/ to give a straight answer, and write this page.
For games from before OS X came out, check the Macintosh page.
And for God's sake, get Steam. It's been available for OS X since May 2010.
Also, Unix and Mac users should look into Wine. It usually supports Windows games and it's free.
By the way, it's pronounced "o-s-ten". Yeah, the X is a 10, roman numerals n' shit.
