A lot of my games have a habit of getting their meshes and textures mixed up. Once while playing VtM:B, in the cab sequence, the cab was replaced by a dinner plate, the driver was gone (but I could still see his reflection in a floating rear-view mirror), the overpasses where replaced by giant clocks, and all the cars had been replaced by non-animated flames. Also, a few of my Xbox games have, for whatever reason, started showing their inner workings (mostly revealed path nodes and plain old paths, kinda ruined the stealth sequences of the games it has infected). Generally, I prefer the game as it was intended, but I tend not to pass up the chance to experience these glitches when they come up.
