I have most online games but I will not add my code not to be rude but because of Nintendo and the chances of people playing on the list is slim. I have had Augen's and we have yet to play DOA hahah.. Only game this feature was good in was Pac man and galaga because all my friends could compete and upload there scores to the leaderboeards and watch each others daily and weakly progress. Outside of that the chances of people playing is always slim inless you set up matches here and if thats the case FC is still little use.
the games i have are kingdom hearts 3D. kid Icarus: uprising, samurai chronicles, and mario and sonic at the 2012 olympic games
Also just a suggestion @ShinobiMuramasa or anyone else that has editing powers. The first post of this thread should be edited w/ everyone's 3DS FC just to save everyone code hunting later when it hopefully gets flooded w/ FC's
