I can't speak for nekro23's library, but mine is ~150 games with 50 available for Mac. I don't purchase a lot of AAA games, but I can go through and list the ones that are/aren't on mac that I would say are of significant quality and a clearly not small titles. On Mac (49): All the Valve games - CS/TF2/Portal/HL/L4D - King's Bounty - Psychonauts - Civ 4 - Trine 2 - XCOM: Enemy Unknown - Two Worlds 2 - The Witcher - B…
Thanks for the list. The problem is that outside of Blizz/Valve's stuff, if you browse Steam's list of Mac games, it's like 95%+ small games made by a lone developer, and that is really sad. No disrespect to those developers, but that kind of games just don't interest me. But you think things are getting better? Do big game studios actually use Unity these days? That would be kind of.. awesome.
Unity is perhaps still predominantly the domain of indies, but the Unreal Engine supports Mac, which is honestly the most important one. Perhaps things will regress a bit with the new console releases as graphical fidelity takes the limelight again and Unity is pushed away by big studios, but I think the point stands that many commercial engines are supporting Win/Mac/Lin/XB/PS and thus there's little reason not to release on all platforms.
Big projects take a long time to finish - the changes are pretty clearly happening but it's going to take a few years.
