DISCUSSION
i hate achievements/trophies so much. Why? Because I'm an achievement/trophy whore... they literally ruin games for me.
For instance, I had Fallout 3 before it had trophy support and I enjoyed the game thoroughly, savoring every little cavern and subway I got to loot and every little note that had a little of the story line attached to it.
Well I sold it a while back and recently decided to pick up the Game of the Year Edition, since I never got to experience the DLC. So I picked it up, saw that it had trophies, got the Platinum trophy within two weeks, haven't picked it up since.
I would mark how I progressed through the game based on the trophies I had. Once I had them all, I didn't want to play anymore. Even during the process of getting them, I would look up the easiest possible way to get them all as soon as I could. And for what? So I could blow through the game and add a couple of trophies to my online profile?
I tell you its not worth it. I miss the days before achievements where conquering in game challenges resulted in a feeling of satisfaction. Now, if I know my actions won't be awarded with a trophy, I won't bother.
So sad. But there's just something so addictive about filling up that little trophy progress bar to 100% or getting all possible GS...too bad its ruining my games :(
