Well it really depends on the mechanics. I could design it so you could only RP within the realm of your political party, so if you lost an election or were ousted from power you'd have to get it back to make big maneuvers, or you're just the leader -- whoever that might be.

One major mechanic will be:

[b]EMPIRE[/b]: [i]While you may have humble beginnings, the academia and learned minds of your civilization have long deduced not only the possibility of extraterrestrial life, but rather the inevitability of it. As we grow, mature and expand, we will encounter new alien species. Allowing them to assimilate and join your culture, or keep them at arms length is an immensely important decision for our administration. Refusal to incorporate could alienate us from a potentially galactic community, extending to them the same rights as our own may dilute our own culture[/i].
