Nice logos (•.•)™!

AG bikes would be fun, but I was thinking along the lines of smaller ships v larger ones- think an hatchback car v an articulated lorry in size terms. An original design goal for me was to break with the cliche of futuristic ships and go for a more industrial look (thus my mission statement 'WipeOut v Motorstorm v British Rail'), with ships getting influences from trains, aircraft, and cool looking machinery.

When I have more time I will scan a few concept drawings.

I am also considering real time damage (like Colin McCrae Rally games), with each ship having destructible parts- now that I can find out the velocity of an object I can assign damage when a ship is going too fast.
