The artificial intelligence for the enemies is somehow wired to the speed of the machine (probably unintentionally). This has the bizarre and frustrating effect of making your enemies in the game play better the faster a machine you play on. On its target platform of a 486/66, the AI worked appropriately for its level. On a Pentium 120, the "easy" difficulty played like "hard". (On a Pentium 233, you can forget about winning unless you're an action fighter maniac and have the special moves of the characters memorized.)
FX Fighter is the most well-publicized game that uses the BRender engine. Rumor has it that FX Fighter started life as a demo of what BRender could do -- a technology demo -- then was gradually fleshed out into a game.
