My own limited testing was actually more positive than expected. The real limiting factor is games that never received a 64 bit update. It turns out that - at least among many of the games I gave a shot - many have received that 64 bit version and run just fine under Rosetta. I think many Mac porting houses / developers just don't rush out in the same way app devs do to support the latest versions, but they tend to get around to it eventually if they still have the rights and are in business. I hope Mac will eventually see a compatibility layer, so games will stay functional while Apple monkeys around with system stuff.
