I didn't know they made a Hearts of Iron 2.5 I'll watch it. But I would've played as Italy or the Ottomans or something. You know, a country that didn't do a whole lot, and then make it more badass than it was in real life. Whereas in Russia you are probably just doing everything as it really happened. Also, which version of the game is this?
Meh, I've tried Italy, it's not that great. The boundries just get really screwed up when you invade Austria/German Bavaria. The Ottomans suck. It's just easy mode at the beggining. Steam-roll the Russians with their four divisions they send after you. I don't even think they have a border with Austria, do they? Then shit hits the fan in the Balkins and unless your prepared your basiclly preoccupied for the next two years.
