there's an "old" game called carmageddon where the physics of the game were like that:
best racing game ever in my opinion. :D
Doom 3 eliminated many of those rag-doll issues by turning off the ragdoll once a certain thresh hold was met, but it wound up with other issues because of it. :)
Very funny -- the old arcade Frogger used to have some interesting crashes in the program. Anybody know what the sound track was from - it sound familiar, but I can't place it.
