New shooting mechanics would be nice too. Something new to look at and non-American.
GTA 6 really needs a new location or several. The problem with waiting so long for a new sequel is that fans will be more resistant to trying anything new so it probably will just be Liberty City, or something similar to it, yet again. Somehow I can’t see them doing it though. Science fiction is all about reflecting the modern world and something like Judge Dredd or RoboCop’s world seems like it would be a perfect fit for Rockstar. They’ve already gone in the past, with Red Dead Redemption, but they’ve never done anything sci-fi and there’s certainly plenty of potential there. The only way I can see for them to change the setting is to set it in the future.
