This was a really difficult list to make, to limit it to 20 games everyone should play. I know there's going to be a lot of upset people because certain games weren't included, but obviously I can't have them all in a list of 20 games. I tried to limit it to games that have aged well, thus excluding titles like Goldeneye 007 or Doom. I was tempted to put Tetris on the list, but I decided to leave it off. I also tried to keep a balance of modern and classic games. Anyways, here's my list of 20 games every gamer should play.
