Any thread like this will have people telling you to buy roughly 700 new games. I'll just say this:
A new copy would run you $30 or less. Good game but don't go spending a couple hundred dollars unless it's something you really want to do. There's plenty to play on PS4 but if the only reason you're considering getting one is because you won a game, I say wait a minute.
Also, when you do get a new console, try to focus on a handful of games. Too many games at one time only guarantees that something is going to be neglected. At best, you'll rush through some games that really deserved your attention.
