I had a quick search and didn't find any thing like this so apologies if it's been posted before. I thought it might be cool to have a place to share games we've 100%ed for systems the site doesn't track. FYI, I'm only counting games that have "extra" content such as collectables, side-missions, unlockable (but not necessarily achievements) that you've collected/ unlocked all of, so there is literally nothing else to do in the game. Currently, I'm going through and 100%ing all the Sonic games on 3/DS. The fist one I've managed to complete is Sonic Rush.
