I'm currently working on two Games. The probably already forgotten Perceptia II, that's been torn down and rebuilt so many times in the last two years it's probably starting to feel like Russia. It's gone back to complete rewrite into an RPG puzzle type game and, unfortunately, is in the paper stage as far as that goes. The graphics are mostly done except for the NPC's; I just have to work out the story line.
Currently though I'm working on another game called Paper Flight. I got the inspiration from watching a paper airplane contest on TV. It started out just as a build your own, then test fly; little more than a mini game really, but it's built up since then. In it you'll be able to composite custom paper airplanes out of different parts, with hopefully about 6,000 combinations when done. How you construct your plane will affect everything about it; how fast to flies, how fast it falls, how well it turns. Then you fly them through races with AI controlled planes, obstacle courses or mini games. Here's a screen shot of the plane heading down a track...
This is my first really attempt at making a full 3-D game so I'm learning as I go. No idea as to how long it'll take but it should be fun. Here's another screen shot of the build centre.
