The disadvantage that comes to mind for me is that some of the games suck. NBA Live for instance is inferior to NBA 2K, everyone knows this to be true. Still can’t complain when it’s this cheap.
It’s called EA Origins for PC. I don’t play of games, so I’m not sure how to set it up.
This is the website, it should help.
