Alternate extreme colonization
I have created a race that gets its colonize world type abilities from super projects rather than research. It seems to work, except for a few issues:
1. There is no ImpStat icon for these 5 abilities. I made some but I haven't checked to see if they will display yet.
2. The map does not update the color for the world type when you build these buildings.
3. I don't know what would happen to some of your worlds if you lose one of these buildings and thus, your ability to use a certain world type.
