Go to Zellers and buy a GameCube. It comes with Paper Mario 2. If you’ve already got one, pick one up for your parents and get them WarioWare used for $15. It’s what I did this weekend and it’s been hella fun at the Rockefeller household this Thanksgiving :) You don’t even need a memory card if your parents are new to games since they’re just getting started anyway.
