Lego discovered gamers want their favorite characters and backdrops to be turned into toy bricks when it released its first wave of Super Mario items. Mario Lego gets new sets all the time, and in March, the first Animal Crossing sets will join them. Sonic has quickly become the video game character with the most sets after his plumbing rival, though. What started as a Lego Ideas submission has turned into an entire collection, and next month, Knuckles and Rouge will join that collection.
