except for the usual thats already said by anweRU

I had one game where spain took Iberia controlled the italian states except for venice afterthat they turned there way to france from some reason there relations turned.

and another game playing as france the ottomans allmost had Austria (they where finished by Prusia)they took Persia and had a region in India

Just to say it al depends I guess had a couple of times that nothing was hapening in europe there where wars but no land conquering (only in the americas) and then from 1745 there were multiple factions gone.
