Prototyping game
(I'm new here, so my apologies if this is too specific.)
I just re-watched Aliens and it got me thinking about where the marines got all their toys, from Bishop the android all the way up to their big spaceship. Now, in a normal-style RPG, players would build the pilots and marines and such as their characters. The lucky or ambitious would maybe get to custom-build stuff, but equipment is usually secondary. What I'm looking for is a game where the players' focus is on designing the equipment, rather than the people who use it.
Sticking with the Aliens example, one character would design the android, while others design the loader-suit, drop-ship, APC, etc. Come to think of it, Star Wars is probably a better fit (what with the clones and all). Rather than gaining improvement with experience, players would be given bigger budgets, higher tech levels, etc.
