While I love Win7 x64, I wish my old games didn't break on it :/ That's about my only major beef with it so far.
How old is old? I've had just the opposite experience. All the games except 1, that I played on my 32 bit XP box play just fine on my Windows 7 64 bit PC. One game wouldn't install but that was because it tried to install a 32 bit driver as part of its DRM. Windows 7 blocked it and the game wouldn't install without it. The last time I looked the game maker didn't offer a 64 bit version or patch.
Other OS:-
My favorite OS is the Atari ST (TOS). It was the first operating system that I have ever used and it was very user friendly.
Really old games (as in Alley Cat old) aren't a problem: they're so old they can simply be chucked into the DosBox emulator. The problem is the stuff around the time of the early Windows games, like say Wizardry 8 - some lucky people can install no problems on x64 but most the rest of us, no dice. It's sufficiently advanced enough to give problems for XP mode's primitive video drivers (S3 Trio, lol, brings back memories). Most Visual Novels don't play nice on x64 either, although XP mode does help with many of them since they don't tend to be graphically taxing.
The less said about intrusive DRM the better - if it does become a problem I'll just pick up a clean version.
