Hmm, was also thinking that politics and contractors would be a great addition to simulate the problems someone like Braun had with the Americans trying to manipulate the US military being first into space, or Korolev had with constant diversions of resources by the Politbiuro in favor of military goals. It would be like a constant challenge(optional maybe for those that didn't want the extra headache) to achieve as much as you can, in order to gain 'prestige points' or something that you could 'spend' on convincing government officials to back your project and not take away funds, or even to give extra funding and support at the expense of other things. You could even 'convince' other rival groups(abstractly) to merge with you and give you technology. If you don't have the prestige points, then you risk getting funding cut or having to give up tech you've researched/built to other projects. You could minimize prestige loss by having your 'hero' pieces focus on this area, but at the expense of not having their benefit for research. This would force you to play at least a part of the game by grinning and bearing government interference if you really want to stay on top in the long run, and knowing when to take a 'hit' such as less money, or having something researched be requisitioned, and when to use your precious prestige points to fight it, could make for an interesting twist to a game.
