Not as easy to do in a realtime 3-d game, I'd guess. You'd probably have to model each enemy's internal biology for the game physics to take hold of, or, alternately, fall back on a series of pre-programmed animations, which in a game like this would probably get just as old as watching slow-mo head explosions after awhile. God, I did love that old animation, though, and the fall-to-the-knees-then-big-wet-thump sound effect that always accompanied it... *wistful sigh*
I guess it didn't make as much sense to them to include death-specific cutaways now that the game is a little more free-ranging and they've so thoroughly de-emphasized diligence in pursuing your main objective. If the design team of the first Fallouts had gone in with the current team's philosophy, there's no way in hell they would've put a time limit on finding the McGuffin, for instance. It discourages sightseeing, which is the name of the game now, and it's a little harder to rub in that you've failed in your task if your current task is, in actuality, rooting around on a mountainside for 'shrooms to eat.
(Who knows, though-- maybe they just didn't want to ask Perlman to do it again. I know if I was as irritated by the process as he reportedly was, I either would've made my participation in the project contingent on ditching that part of it or I would've told them I'd be needing more money than they were offering to go through it again.)
[spoiler:205a797825]I liked that Dead Money included an ending narration for you if you (for some unfathomable reason) decided to seal yourself in the vault, though. I thought that was a step back in the right direction, as it basically amounted to "you're stupid, you died."[/spoiler:205a797825]
