an open-world GT simalir to Forza Horizon.( with weather and night/day) Still GT though. (gonna get "rip-off" comments too.)

Or

a Resistance : Crimera collection to see if there is still interest in this series.

Or 

Ratchet and Clank: Future collection.

It won't hurt if sony do this right?

Resistance collection, R&C is already getting a reboot. I don't know if it'd be a good way to measure interest in the series though, in practice it only measures interest in the remastered rerelease of old games, not the potential market for a new one..

GT game like Horizon.

Being someone who love the Horizon games this is a no brainer. Would love to see what Polyphony (?) could do with the series as well.

Though a R&C Future collection would be greatly appreciated!

I would rather have a GT style rally game with tracks all over the world.

The GT game, without a doubt.

open world gt game

Resistance, loved and played the fuck out of the first one and loved the Bullseye for being able to tag enemies and just pull the trigger until nothing is left but a ball of bullets, Auger was also a cool weapon to use, in fact most of the weapons in that game were pretty inventive with their second abilities.

Yeah, I would like an Open world GT too.

GT of course.
