Every game that lets you tweak the settings to that extent can be 'broken' quite horribly. A really good example of this is Bethesda's Elder Scrolls games. While very entertaining, a determined person can 'game' the system and then you've got an over-powered character running around in the game environment.
I can see how this would be fun for all of five minutes. Once the novelty of 'Hulk smash!' wears off I think I'd become bored very quickly.
