I haven’t played jc3, but I plan on it. I mainly played jc4 cause I just love the environments, and the diversity that comes with them. I had a very distorted perception of just cause 4, though. I must be thinking of some other game, cause I’d always seen it as a more gritty, dark game, but from screenshots I’ve seen it looks really vibrant. might check it out sooner rather than later
