Let's see:
- Ridge Racer? No, already appeared on 360, so not big splash...
- Tekken? Probably, but IGN said another franchise.
- MotoGP? No, THQ has the rights to MotoGP on 360.
- Time Crisis? Too much trouble to bring gun games on too many types of nowadays HDTVs.
- Ace Combat? Sure, why not? But is that big?
