I like the idea of a multiplayer game in which players end up regularly shifting sides through a forced rule mechanic. In effect, you must be the best steward possible whatever you're doing because you might end up playing from that perspective in the end.
I really like this idea. Though it takes away from seeing your game spanning strategy come to fruition for one entity. Are there any games in the consim variety that use this mechanic?
Most of the multiplayer opportunities I get are with two of my nephews. It always ends up that whoever jumps to the perceived lead is blown back to the dark ages by the other two banning together. Most likely it's just our family dynamic.
