[Phoenix-D]

Here's another concrete example:

In SEIV, many mods implimented "native" colonization tech- that is, if you started out as a Rock dwelling race, it was harder to research Ice technology, and vice versa.

In SEIV, this took three racial traits. In SE5, it can be handled with three tech areas, WITHOUT any interaction from the player at all. There's no confusion and no extra racial traits.
