1. 7 / 10
2. Not as much as my PC (which isn't much to begin with) but enough, usually for impulse sessions but clocked in 15hrs in Most Wanted U alone.
3. Used to play Tekken online almost everyday then Most Wanted U came along. I have a bunch of other games that I'm not close to finishing
Other thoughts. Frequently feel buyers remorse tbh. I wish I bought a cheaper 7th gen SKU to fill in the gap before getting a PS4. This could change over time but I doubt it. I feel I could have spent my money on something else and barely felt a thing :/
