I'm often prone to hyperbole - but this is truly incredible. Gareth doesn't have the use of his hands, but thanks to some games offering the ability to fully customise controls, he has somehow found a way to continue gaming, as you can see from the videos below.
After complaining in an Overclockers forum thread that he couldn't play Dead Space 2 as a result of non-customisable controls, and having someone question why he would need customisable controls in the first place, Gareth responded with the following videos, showing how he rigs up controls in order to continue playing games, despite not being able to use his hands properly.
It's an incredible story, and one that has resurrected interest in this petition, which asks that all games in the future ship with fully customisable controls to help disabled gamers set up controls specific to their condition.
In addition, the folks at EA have gotten in contact with Gareth directly, promising to add the custom controls he needs in the next Dead Space 2 patch.
Thanks to 'ghst' at Neogaf for alerting us to this awesome story
