If anyone you know wants to get into video games in general, let alone platformers, tell them to play Super Mario Galaxy. This almost flawless showcase of creativity and wonder is a triumph for the industry and will be looked back on as a work of art similar to how the Godfather is to movies in todays day and age. If this can't get you into gaming I don't know what will. This may not be my favourite game, but it is probably the greatest that I have ever played.
I was given this game when my friend said it "gave him motion sickness". This game never gave me motion sickness, but it did give me my favorite 3d platformer of all time. I love every single level, and it's all just so satisfying. Nintendo fucks up pretty much everything they do but they know how to make some good games.
