Personally I only use cheats AFTER I've beaten the game several times. I've played both KOTOR 1 & 2 several times without cheats or mods and decided to play the games again using mods and the cheat codes this last time around. I found that I didn't like using the cheats on the first game since somehow Bastila's conversation about her mother never comes up. When I went back and played without the cheats, in the same manner as with the cheats, the conversation came up.
Frankly, I don't think it's my business if someone uses a cheat or mod UNLESS it's in a multiplayer game and have an advantage over other people.
