It's not perfect, but it's definitely one of the best games I ever owned, (That puts it up with the likes of Xwing, Descent, Star Trek Bridge Commander, Civilization, Master of Orion, Harpoon, the Jedi Knight and Mechwarrior series', Homeworld, and Flight Simulator, that's saying a ton right there!).
I paid 40$, and consider it a real bargain, as I fully expect to be playing this for many years.
And how about a big 'Hurrah!' for all the modders who've taken a great game and made it look even better, run even better, and fix a number of issues some have with the game. Ubi rocks for making it moddable, and the modders rock for stepping up to the plate.
