SLUDGE Engine

SLUDGE has always been great. But now, it's also a programming language. SLUDGE (standing for Scripting Language for Unhindered Development of a Gaming Environment) is a system by which anyone (within reason) can make an adventure game.

It runs in any recent version of Windows and now also on Mac OS X and Linux. It's high-res (any resolution you want) and uses 32-bit colour.

To make your own SLUDGE games you'll be needing the SLUDGE Development Kit; to play the games, the SLUDGE Engine is required (it's included in the development kit download and should typically be distributed along with the games).
