I am reposting this for a few more responses... sorry if you already seen it.
I never played GalCiv1 and I know this has been a hot topic in a past... but how about a space monster mega event for TA or 2.0 patch? Maybe it only hangs around around for a few turns... maybe it creates a high PQ planet as a nest and guards it in orbit (like the dread lords mega event). It doesn't necessarily have to roam around and destroy things (although that would be cool too ). I think it would add a little variety and could be fun.
What do you guys and gals think?
