I feel sorry for anybody trying to buy every PS4 game in existence, there's something like 4000 or more physical games. All I know is that if you come across a cool looking game in a store and pass on it, there's a high probability you'll never see it again. I've done that too many times. Didn't buy Cannon Spike for the Dreamcast, never saw it again outside a game convention. Ring of Rose for the PS2? Passed on it, goes for something like $600 now. Yikes. So if I find a game that looks fun and it's at a reasonable price, I try and grab it.
