I think this might be a game I'm looking forwards to as much as GTA. I was interested in the weird floating block things and the ink and always love a 60s setting. Then I played XCOM enemy unknown and got into that a lot - maybe they've held this back to merge it more with the traditional gameplay as I hear hardcore xcomers were raging over this games fps/tps status. I for one like the concept, hope it's as good as I think it could be.
Trianglular Sandwiches advocate against remakes of games, except Halo MC collection and GTAV... and metro... and minecraft.
