Woot! I just won my first sucidal victory.

With everything but research randomized (research was set to slow).
Unfortunately, it was the second metaverse game I'd played. My first one was on normal. And only now do I realize the metaverse difficulty levels are averaged.
So my pretty sucidal-level victory is now downgraded to a crippling level-o-play.
Can I somehow delete my first game (which I used as a warm-up to the metaverse) or am I stuck with it?
