Let's say that, suddenly, Nintendo decides they won't be as overprotective to their IPs and Gamefreak collaborates with another videogame company to produce a pokemon game.

How would each current videogame company handle pokemon?

I'm thinking Valve would be the ideal situation here considering how they put so much work into story and detailing their games, wich is something a lot of people complain about in pokemon. They are also really concerned about gameplay and take their time with the games and would probably include a lot of things they know the fans want.
The only "problem" might be the time they took to make each game but with GF's tendency to rush they could release a game each 2 or 3 years, wich would be ideal.

So /vp/, what other companies would you like helping GF out?
What companies would make you quit pokemon if they helped GF?
