I did the same for sure, played every native linux game there was but at the time most of the game I played were rough under wine. CS: Source, TF2, L4D, and WoW were all pretty hard to get reliably running especially compared to their windows performance (note, this was 2007-2009 range). I still remember a youtube video showing WoW running on Wine and they had Compiz so you could see WoW running then they switched (using the rotating cube transition) to another desktop. The video claimed it was getting higher FPS on Linux+Wine vs Windows so I of course dropped everything to try it.... I did not have similar results.
Heh, my time with Linux was before then, I think - but only by a couple of years. I do recall having some fun experimenting with StarCraft and NFS: Hot Pursuit (the og 1998 version, not the 2010 remake) under Wine, though.
