To those who are interested, Europa Universalis IV is on sale for €9.99 for this weekend. I'm going to assume it's $9.99 too. It comes down from 39.99, so it's a beautiful deal for an awesome game that is still continuously updated and has a massive community-generated mod base. Just thought I would share this information.
Edit: it's also free to play for this weekend. So if you're not familiar or not sure, try before you buy!
Hmm, and it's cross-platform...I'm going to have to seriously consider this...
I've had a blast with both this and Crusader Kings II. It was really fun building a completely cohesive Turkish Sunni Ottoman Empire (no tolerance for us!) one game, only to do a completely decentralized, full of different religions and cultures Ottoman game the second time.
