I wish Spore had a God-mode where I can just sit back and watch the creatures I create survive and fend for themselves. I get to drop in Rogue and Epics creatures to see how they react. Or I could put a social creature surrounded by all aggressive creatures to see the results.
Spore update: Have been really digging it - a really interesting game so far, but it's feeling a little directionless currently on creature stage: can't seem to make friends OR kill anybody right now, in a loop of trying and failing and dying. Blurg.
