As you can see from the fact I've merged your thread, this has been brought up before. I thought it had been discussed in more depth, but I can't find the thread(s) now (probably lost in 2005).
Personally I've never tried one of the specifically anime base P&P RPGs, but only because the people I play with most frequently are not
that into the themes on offer. I can't imagine Panty Explosion doing it for me
. Anime is a broad brush though, so elements from many of the shows I like can be found in many of the games I've played. In fact, having said that, I suppose I have played one
technically, as FASA were forced to remove the LAM
'Mech designs from their BattleTech game because of the striking similarity to Macross variable fighters
Incidentally, we also have a
group devoted to exactly this topic.
