We've got a few games in the pipe, and none of them are open-world. It's a common assumption that games with some procedural aspect come out as sprawling "canvases" for free-form play — that you'll be stuck in the sandbox if you want to play with procedural environments. Where in fact, our game currently in active development has a tiny environment. You can see the whole thing on one screen, with your character occupying about 1% of the area. The environment is continuously procedurally generated as the game is running, constantly shifting and changing without really expanding, per se. The player's reaction to their ever-changing surroundings is a big part of the fun. The gameplay is rooted in kinetic action, where spacial relationships are manipulated by the player. It's an arcade-style game, with the player's character pitted against a screenful of enemies. Attacks don't cause damage as much as create movement, and it's the movement of the character and enemies with respect to the (somewhat predictably) shifting environment that creates the flow of gameplay. I'd be more specific, but we're not quite ready to reveal the whole concept. It's quite a bit different than anything we've seen before, so we're being careful about having the product ready to launch before we start showing off the more unusual and exciting qualities.

In addition to procedurally generated, constantly evolving environments.. we've got procedurally re-composed music (my background is in algorithmic music composition). Re-composed, meaning the music is based on human-written themes, but the arrangements are done in realtime by the computer. We're also playing with procedural generation of enemies, to create a lot of variety with relatively little effort. That is, they'll look and behave differently depending on the outcome of the procedural generation.
