Not versatile because its huge. Maybe if you have a Blue Galaxy at a high level then its good, but other than that, compared to good event buildings, its not good. It requires population too. It doesn't require aid, but it can also be plundered. Yes, it has a plus point that it can be used to do productions, but that still doesn't make it as good as, for example SoKs. Doesn't give coins either. Maybe if it could be shrunken to 5x5, there could be a decent comparison.
