A bit of a late reply, but I wanted to say that I too, consider whether a game has cheats or not when making a purchase. Although, for me, this does not apply to every game. Generally, if I'm buying an FPS, I tend to purchase the ones that have cheats or the likelyhood of a trainer and tend to avoid those that don't. The reason being that I buy games for enjoyment, not frustration. And there's no point in buying a game if I know I'm not going to be able to complete it. In that respect, having cheats in a single player game is very helpful.

However, I do not feel that Mayhem Intergalactica needs any cheats -- epsecially in single player -- unless those cheats are to help make the game harder. I'm not a brillant games player, but even for me, this game was a little too easy in respect to the AI (on highest settings). So the ability to make the game more challenging -- not less -- would be nice.
