Meh. I think my province count was something like 18 by 263. Blitzing was a strat that I found back in the days of MTW.

People used to complain that the MTW Turks were the hardest faction in early. I showed a blitz strat that would more than triple the treasury on the second turn (on expert mode, comparable to VH in RTW).

I did blitzing ever since. I've frankly found every faction to be fairly easy as it's quite possible to double or even triple your empire in the first 5-7 turns. The AI just cannot deal with blitzing.

Also, due to how little it is into the game, you can plan for exactly how many units you will come up against as starting armies are fixed.

The strat is a bit too effectively however. It really takes the challenge out of games.
