Ahhhh I remember when I decided to give up my ways as a non gamer and turn to the light side! Seriously, welcome and I have a few suggestions. I recommend going for the basics right now, good and cheap. You cant go wrong with the nes(easily available games and cheap prices). The games are fun to play. Not knowing what you like, I would take it from there. If you like 2D fighting there is always the Dreamcast(Cheap and awsome 2d fighters.) There is so much to choose from.....I suggest to dive in, get one system, and play some games!!!! From there, you can decide what you like and what you dont. Welcome aboard, grab some gaming fuel(mountain dew, doritos) sit down, and plug in!!!
