Watiggi said:Oh btw, I think the +2 scientists means that the city can have an additional 2 scientists on top of what the library already grants (which I think is 2). I don't think it means literally 2 free scientists - it just lets you allocate 2 more scientists.

Maybe there's another posibility: Perhaps the +2 scientists for the russian UB means "Generates +2 Great Scientists points per turn". It makes more sense to me. It is not underpowered or overpowered, and the interesting thing is that permits the generation of GP without building a great Wonder or turn a citizen into specialist (by the time you get Literature it's best put a citizen to work a tile instead of turning him into a specialist).
