Victoria 2

[Akar]

How complicated is it compared to HOI3?

[tarvu]

Quite a bit more (other than combat), but there is already a thread discussing the game.

It really depends on your play style. You can run a Great or Secondary Power without paying much attention to details, so you can get into the game pretty easily. You don't have to learn everything at once. But if you want to maximize your efficiency or play smaller countries, you'll have to be more nitpicky.
