One of my current projects has the working title of "Cannoneers". Ultimately it will be a turn-based game where players run around shooting at each other, along the lines of the 3D versions of Worms. Shown below is the Avatar I've built for it, which should give an idea of the style I'm aiming for.
I decided to go with "tiny" avatars, because it adds a sense of fun to things. It's also good practice with the anim overides, squashed anims and invisi prims that tiny avatars rely on.
The animations are done, and cannon power is controlled by how long you hold the mouse down. The next big feature will be controlling turn taking.
