Me and a friend at work had a conversation about this the other night.
I'd love to see them start another story arc. I never played the first one but 2 and Future Perfect were terrific.
Put countless hours in on them both trying to finish the arcade leagues and challenges.
Some of the challenges were just nasty. Few of them that I never beat. My friend claims he had platinum medals on every one of them but I've never seen this with my own eyes. Just asked him if he was sure as im pretty positive he'd be one of the only people in the world to accomplish that. I do know at one point he was basically obsessed with those games.
Anyways, I think Timesplitters could make money. The series actually has a pretty solid following.
