I got a partial implementation here:

You can register and make weapons, that's about it for now. Still have to do buying and firing weapons, and then I'll move on to the non-essential profile pages and profile editing. And a big reset button since there is no end-state either.
I don't intend for this to be used for any CURRENT games, but for new ones. Or something.
Rules need to be tweaked a bit IMO, EX Pommy's weapons have little R&D cost but he can still earn as much as anyone else and they can still do as much damage when bought and fired in bulk. Solution would be to either restrict the number of other player weapons you can own at once, or to make it that you can't fire more than one weapon at a time until someone else fires a weapon, then you can fire another.
