A beta of Crossover Games (it’s a version of wine if you’re not into this stuff) has been announced for FreeBSD.
Currently there’s one crossover developer porting/building it, and he asks for community support on their pledges page (i.e.: if you do buy it, even if not very functional, and go on their website saying “hey, make it work”, they’re going to try and make it work)
edit: there’s an RSS feed for FreeBSD support
