I'm ok with the tenchu thing, but I don't really approve the survival horror thing for these reasons:
1. Most characters have guns, the original games were not focused on martial arts.
2. Some of those games were based on psychological things, like silent hill.

I think other games which can be turned in fighting games, in my opinion, are:
- Rogue Galaxy, soulblade style
- Crash Bandicoot (why not.. we already got a kart version of it), ssmb style
- Incredible Crisis (yeah i know, that would be a totally weird but extremely funny fighting game)

now, "for something completely different":
- GRANTURISMO (ok, just kidding :D)
