This caught Mr Chalupa's eye, and I thank him for bring it to mine. Super Mario Bros Crossover is - as the name suggests - a bastard-pop mash-up where you play six NES-era characters in the original Super Mario Bros, selecting who you'll control on each life. Efficiently done, though I'm surprised they didn't make each character's life be a single life, forcing you to select other ones. Equally, being very much in the gray area, I suspect you should - er - play it quickly if you want to. Mostly though, being a Brit of a certain age - as in, without period NES experience - I didn't have a clue who certain characters were, and had to sort of deduce that the brown-smudge was probably the guy from Castlevania. Don't select him though. He's rubbish. And don't select Link because he's eminently punchable. Play here.
