Just finished playing a 3v3 Europe 1600 map. I noticed that the bonuses for the Ottoman empire were raised, slightly, before the game began. Obviously, the bonuses need a bit of a boost in that area, otherwise you end up with 7 territories for a 3 bonus. What I thought was a bit interesting was the choice. When most people play this particular map, they rarely go for Ottoman Empire. Thus, if you are able to make it worthwile, you know you can expand pretty much undisturbed for a pretty good amount of time.
I wouldn't call this cheating, or even particularly underhanded. The bonuses really do need a boost. I even tried to counter what I knew would be Osman's strategy, but unfortunately got too tied up fighting in Germany/Austria to advance quickly enough.

Again, I am not complaining about stacked bonuses or crying for anyone to blacklist this player. Really, the most annoying thing was the 75% luck, not the bonuses.
