"I had just got back from a party where the concept of a Pac-Man + Zork hybrid came up as a joke. So, being 2am with a little alcohol in my system, I thought it'd be funny to code it up..."
And thus began, Pac-Txt, a browser-based text adventure, based around Namco's seminal pill-munching coin-op. The author has since programmed some 'crappy AI' for the ghosts and included some simple graphics. Having already been featured on CNET, the site could well be attracting a lot more traffic than the creator expected - which will probably mean we can expect more drunken retro mash-ups in the future. Guantlet? Too obvious. How about Donkey Kong?
Actually, I think any of us could knock up an Asteroids adventure in BASIC. Anyone fancy giving it a go today?
