Yes we both bought generals - it was our first play - they just seemed cool.
There just seemed to be so many IP tokens, so just wanted confirmation if we were playing it right. Perhaps there were so many for 4-5 players that threw us off.
Great game though. Very clever. There were a lot of phases and steps initially, but once you get used to the pattern its pretty easy.
I think you answered it - for 4-5 players, you use a larger map with more resource locations, hence the need for more tokens.
