The persona- Oh. There's already plenty of anime on that. I guess it'd be nice to see some more anime based on the main Megami Tensei series, though. There's a few OVAs, but not much else as far as that series getting any adaptations go. I wouldn't be surprised if one of those OVAs was based on the book the games started out being based on, though. I could see Sly Cooper being an awesome cartoon. It already has all the elements.
Not much else I can say I want to see get such a translation. Not many games would work with other media types. The Persona games already are like a slice of life anime, so they seem to already make sense enough. I would say Yakuza would make a good movie, but the story unfolds through gameplay far more. Devil May Cry already has an anime. Don't recommend it unless you seriously need a Devil May Cry fix that doesn't involve playing the games.
Pokemon already has had tons of movies and a too long anime, but I'd love to see the Adventures manga get an anime. The manga toned down on the weird violent moments pretty quickly, so there'd be no need to worry about Pokemon being cut in half.
There are a few video game based shows that are good or at least decent. Most just are cartoon in most cases. Probably because it's easier to stay true to the source if you don't use live actors.
