You need to understand this: while you'll have a great time here, learn some fun things, and get great games for cheap, you're not going to save money. You're going to spend, spend, spend and buy more games than you ever have hope of playing. You'll have piles of unopened games and spend days on end deciding which game to play next. You'll discover games, nay, genres that you never imagined and realize that you must own them all. You'll buy accessories that you never imagined you'd be interested in and storage systems from plastic crates to shelving units to store your newfound bounty in. It's all going to be cheap, but you'll have less money in the end.
I wouldn't have it any other way.
