I hope I notice this discussion earlier. It is interesting to discuss these consoles and their development over the last few years. I never had the chance to get other than the PS2 and PS4, but pretty much enjoy playing on PS4 because of the remastered version of the other games.
The most hours I've spent on a console would have been the PS3.Just due to my age, being at uni during that time, and being the console with online connectivity (not that the PS2 wasn't online). I love all of the previous gens and current gen. However PS3 has that spot where it was all happening fresh (and PSN was free back then).
