LOL well when I take yours it isn't intentional. It's usually just games I haven't played before that you happen to be champ of.
You can take back whichever one's you like, I'm just playing. Some games (like the dumb fishing games) I really like. That Spongebob bowling game is a riot.
But, the only trophies I try to deliberately take are Imperium's. I have most of his now, as a matter of fact. He doesn't have very many left.
And soon, they'll all be gone, except for the ones he actually cheated at, or can only get a certain high score at, and those aren't a challenge anyway.
