Look back into history
If this looks familiar, then there's a very good reason for that. It's basically a rebranded version of Europa Universalis II
but with some bug fixes, mod integration and the addition of Gameranger support for multiplayer. It looks a little dated today but as far as deep, rewarding historical strategy games go, this is fine stuff. This one is pretty epic in scope, and you can take control of any one of 180 different countries and it's your task to guide them through history. You've got to make decisions on pretty much everything imaginable, from diplomacy, to trade and combat, and the game takes you from the early fifteenth century to the early nineteenth, so you can expect to see some fairly radical changes throughout the course of your adventure. There are thousands of historically accurate events to take part in, and much of the appeal comes from seeing how your decisions affect the course of history. This version includes a smoother interface, making it a bit more accessible to modern gamers, but be warned, this one has a pretty steep learning curve. If you're prepared for it though, you'll find a thoroughly rewarding, engrossing experience that will have you hooked. There's so much depth and variety on offer here that it's easy to get sucked in, and there's no denying the sense of satisfaction that comes from building up your nation and taking it toward glory. The visuals might not be that impressive, but it's the depth that's the star here, so if you want to lose yourself in the past, this is the perfect way to do it.
