When I first got my 3DS sometime in 2012, it came with Mario & Sonic at the 2012 London Olympic Games, which I briefly played just so that I had something to play before I got Super Mario 3D Land the very next day. The former was surprisingly (less so because it was made by Nintendo and SEGA) decent, even if some of the sports in there were crap - for example, the football (soccer) was just penalty shootouts. I'd have rather seen an actual match.
