Rob Williams of TechGage has written an article on the top 10 free linux games. The criteria are as follows:
So how does a game make this top 10 list? Well, from 10 – 1, they have all been listed according to how many votes the game received. Though there were around 50 games total that were brought up in forum posts, most only had a single vote. Even our #10 had only four votes, so it's obvious that the top games are there for a reason. In order to qualify for the list, the game had to meet these requirements:
Has to be 100% free… no strings attached.
Cannot require wine to run.
Open Source not a requirement.
Installation must be painless.
Cannot be an add-on to a commercial game.
