Skyrim, runs great on my ps3. although I believe you should buy it for pc, if your pc can handle it because than you'll be able to download modds, and all glitches bugs that aren't fixed by bethesda themselves will be fixed by modders.
but I haven't run into a single bug or gltich until now and I have been playing since saturday. know that I think of it, a little bit earlier my game did freeze and I had to restart my ps3, but it was the first time it happened and it hasn't happened again. perhaps it had something to do with the fact that I was already playing for more than five hours, none stop.
