Idea for PBW game your feedback

[rextorres]

Hi All,

I am looking to start a PBW game where everyone has a different victory condition other than Last empire standing. Hopefully this will encourage more interesting play other than just search and destroy, and give players a chance even if they are behind the bigger empires. Each player would keep secret what there victory condition would be.

Some thoughts I had for victory conditions were the following:

Player 1 Xenophobe - Build Ringworld
Player 2 Warlike - Be the Last one of two players(the purpose of this one is so that the game doesn't degenerate into war because everyone knows that if players wipe each other out someone will win)
Player 3 Peaceful - Survive until turn 150 (the purpose of this one is to promote some fighting and urgency cause everyone knows that someone is just trying to wait out the game)
Player 4 Gnome of Zurich - Have an income of 3 million in total resources for 10 turns
Player 5 Technologist - Have an income of 1 million in research for 10 turns
Player 6 Slaver - Relocate at least 100 million of each race to your home planet

Do you think these would be fair or how would you tweak them so that they are not impossible or too easy? Does anyone have additional suggestions for victory conditions?
