Open world GT would be great. I'm really liking Horizon 2, would love to see Sony make their own type of "Horizon-game".

All of it sounds awful. Where is my Motorstorm collection?

not into racing games. So not the GT
only played the first two Resistance games, so it might be fun to finally have trophies for the 1st, though I'd really rather not play R2 again unless they had co op for the campaign like the first.
R&C also like Resistance the 1st had no trophies. So it would be fun to play again, that and I enjoyed them so probably this option.

Ratchet and Clank: Future Collection would be great .

I'd go with the Ratchet and Clank: Future collection, myself. Never played a R&C game, so that would be a good place to start.

Resistance collection

If I was forced to choose between the 3, I would go with resistance. If I wasn't forced to only choose between those 3, I would pick none of those. I'm not a fan of racing or rachet and clank style of games. Resistance was alright. If any of those would sell well enough, it would be worth it though for the companies.

GT easily

After some quick thinking, an open-world GT game would be awesome. The GT series needs to lax up a bit; it has gotten way too hyper realistic in the simulation aspect. Open world might give it a breath of fresh air, even if people complain that it's a copy.

Damn...
