I had Crysis/MWLL running in Wine as far back as 2008/2009-ish. It wasn't free from bugs (example) or crashes, but you could play. That was the 32-bit version, 64 bit didn't quite work yet.
I'm glad others are still looking into it these days. I've stopped since getting a dedicated inferior Windoze machine for games and such.
The Funbockses have been running in Wine from day 1 and work very well. They even work in 64-bit, if you can live with a very weird bug.
