PS4 lost, no bavckwards compatability, they wont let you take your games over multi peoples houses to play, so trade ins are a non option, VIdeo game stores bout to go straight outta business with this dick move.
wait i don't get it what you mean take the whole system to your friends house though...

i waited 2 hours just to see a stupid ass controller fuck you sony
nah like if you bought a game and say I was like yo Bring that game over so we can play. Youd be limited to 2 systems max, they got some sort of gay game code that only allows two system usage tops. You wouldnt be able to bring it to another persons house and play it.
limited to 2 system max like for a ex if you took it to 2 different house, you won't able to take it to the 3rd house if yes then wtf thats stupid how can you resell that shit if you want to get $$ for that shit.Even if you lose your receipt
