I have been a long-time fan of this game. So much so that after I stopped using PCs and ended up using Macs as my primary computer, I actually missed playing it so I bought a gaming laptop so I could play it again.
Amazing and very addictive game that is, in essence, an RPG. Highly recommended to all RPG and strategy fans who like bits of grit.
There is also a smaller browser edition of this game called Europe 1400. Also very fun to play casually. Obviously it isn't as great as the original game, but it's still great.
