Well, playing in a previous H/H turkish campaign, I quickly seized Asia minor and blocked the 2 land bridges going in. I toggled fow off after many turns to see what has happened during the neutrality period and it seems HRE always gets squished much like my other campaigns before. It also seems Poland and Hungary expand very fast, combined, they occupy nearly 2/5 of the whole map. Most of the other factions mainly the northern europeans don't seem very active, they move around for a while and hit each other and then retreat and sit around..must be the cold air
