From TechnoBuffalo: "The side-scroller was once the gold standard visual style in gaming. Platformers, adventure games and even some great puzzlers were done in a side-scrolling format.
Then came the Nintendo 64 and the era of 3D gaming on home consoles. Side-scrollers became a sign of age, outdatedness and niche, unfortunately. Now, this current generation of machines steps up to the plate. Side-scrollers, both on the Wii and downloadable marketplaces, are enjoying a great resurgence in popularity."
