Serious question. Why do gamers or fans of the gaming hobby sometimes seem so cheap?
Gaming is not that expensive after the initial buy in. A game at full price every 2 or 3 seems plausible.
But to answer OP, ARMS. I always buy new. I only buy used if I really forgot about the game or didn't know about it.
I have two rules. If I am going to own ot for life, unless it is on switch, I will buy digital. If I know I will not hold on to it I buy physical and either beat the game and sell it as fast as I can or sell it on bundles to buy more games. In the emd the hobby pays for itself in some ways.
Edit: whelp I did lie a bit since I have GC and Prime. So no real full price for a bit, but I didn't mind when I did.
