You know, it used to be games were made to be fun.
I started gaming with Doom and this is when I started thinking games were meant to be made for me to have fun. So for years I would buy games with the coolest covers.
So the last terrible terrible game I played was Homefront. It was like Call of Duty but more frustrating. In fact both of them were designed to torture the people who bought them. The only reason to buy CoD would be for it's multilayer. It wonderful multilayer community who will call you obscene names on a mike for having fun
So if you just want to have fun. Don't play games like EVE online, World of Warcraft, or Newerth. Those games were designed to be purely purchased.
