I have not played any recent Mario entry since the Wii (i.e. Super Mario Galaxy 2), and I think I want to buy a Nintendo product soon even though no one in my social circle owns the most recent Nintendo products.
Super Mario 3D Land or World?
New Super Mario Bros. 2 or U?
Mario Kart 7 or 8?
What elements do you like/hate in each version (e.g. platforming, level design, rubber band AI, items)?
What makes one version better than the other? (e.g. mobility vs. console)
