Worth the money, allthough it suffers from ubisofts **** DRM
Anyway, the game itself is wonderfull, both graphicaly and gameplay-wise.
Gameplay-wise, The campaign is not something to get exited about, the freeplay mode on the other hand is really something with wounderfull micro-managment and some satisfying rewards for playing.
However, there are a LOT of bugs ( i think they are bugs), an example is that trade-routes dosn't seem to work for me, i simply can't choose a ship to trade for me. So i have to do all that manually which can really be an ass-pain. And my ships won't show either, so if i've accidently left one out on the map, i have to search the entire thing, seeing how there are no icons for them on the mini-map.
And Graphically the game is really quite good, with wounderfull animations, and stunning detail at some units and buildings.
So, all in all, the game is really, really addictive and good, allthoug it has some major annoyances it's still so fun you can look past them.
