Any details on how this might work?
Well, there'd need to be badges according to the type of win. I suppose that's the easy part.
Then we'd need to have some minimum requirement on screenshots for submission. Maybe there could be a check-box in the settings where the game automatically generates screenshots when certain events occur: Elpuri dying, Oree dying, etc.
Then once the player reaches the high-score screen displaying a victory, the player gets the option of sending the victory info to attnam.com.
Only downside is it might be open to spam or fraud. I suppose it would only make sense if the player was a forum member...
