I know this is prolly not possible but I wanted to say it anyways:
I wish there was a way to verify that an achievement was obtained fairly (without invedit, etc). I'm getting all of MY achievements the legit way, which I think is more satisfying.
I've felt (for a long while) that if invedit is used, there should be a small but permanent stamp on the screen inthe top right corner for JUST the world that invedit was used in. Just so we know whats really going on in screenshots. Of course it could be photoshopped out but hey its a start.
What do you think? Do you like the stamp idea to verify more legitamately obtained achievements?
