Imperial glory ! Can't find any other game with that kind of gameplay, it's like Rome total war but napoleonic era. There's the whole map of Europe.
And no, this is not like Napoleon total war, I played it, and it's stuck on historical accuracy and you don't have an entire map where you can do what you want, which basically sucks because this would give the game all its value, but that's my opinion. That's also why I don't play NTW.
2001 game, I'd say underrated, never met anyone who knows about it. Can't post a link due to my new account, if you will excuse me !
