This is what Super Mario Bros looks like when it's played on four wide screen computer monitors. It looks more than four times better than before. There must be tactical advantages too as you're able to see what's coming up.
If you haven't play Super Mario Crossover, I totally suggest it. It's just like the original Super Mario World game, but you have the option to play as other famous Nintendo characters, such as Link, Samus, or Megaman.
