Over the years it has become clear that if you are going to buy Team Fortress 2 you should buy it on the PC. Valve continues to support the game with awesome content that you can only get if you are playing it via their steam client.
Valve have made this fact even more… Factier! You can now submit content that you make on their submit page. If it is approved it will be put into the game and you will be given a unique version to show off. All user created items will be added to the random drop list and everyone will have the chance to get your item. But remember! you had your item first, and yours is better!
