Caved in and bought the PC version. The graphics are simply glorious, and run at a more or less consistent frame rate (Phenom II X4, 8 GB DDR2 RAM and a Radeon 5770 here). The 16-bit levels were lovingly recreated, and the race against Metal Sonic was pure awesome nostalgia masturbation. Speed Highway and City Escape were pretty meh (the Classic Sonic version of Escape from the City was pretty good, sans the vocals and awful lyrics shitting it up), just like the originals, but Seaside Hill was beautiful, and not half bad this time around. The controls aren't as good as they were in the classic trilogy, but they're serviceable. Haven't played Colours, but so far this is probably the best Sonic game since S3&K, even if it isn't perfect. Which is sort of sad, in order to get a good Sonic game out the door, Sega has to resort to rehashing themselves. Oh well, can't complain.
