HSP

HSP (Hot Soup Processor) is a free Basic-like language developed with the main purpose to create 2D/3D games and multimedia applications. HSP fully supports DirectX and has a large community which provides libraries and applications. HSP is an interpreter but can build stand-alone EXEs starting from 100Kb. HSP is very famous and popular in Japan. Unfortunately the English ducumentation is really poor. A Macintosh version also exists.
