EPIC GAMES FOR EPIC PEOPLE!!! (BL2 and so much more) FREE GAMES!!!

This group is for people who just want to play the fun classics together or talk about the best games on the planet.
Right now i'm just starting so we don't have any dedicated servers, so if you want to play epic games with a fun group of people i'll find some fun servers that I take no credit for. Please help by recomending good servers for the games that we play. If you are some of the first people to join I'll try to reward you later if I hit 100 members. I use steam all the time, so this group will stay updated!
