Been playing MOO2 since I was a teen, and this is a worthy successor. Some things are changed, and some of those I'm not such a fan of, but the positive far outweighs a negative. Recommendation: Get the UCP patch and 5X (and associated) mods.
I played a lot of MOO2 as a teen, and this is definitely a modern successor. While I have a few quibbles with the changes made (i.e., the warp-path system), none of them are deal-breakers. I still enjoy it, but recommend you get the Community Patches.
I've heard a lot about the game, and it seems interesting. From what I've gotten through of the gameplay so far, it should be fun to play. However, this is clearly a straight port from a console (either XB or PS). The tutorial asks for use of XYAB and triggers; no clear keyboard equivalent. Also, I got stuck in the menu on my first play-through while I was doing the tutorial, and had to crash the game to get out. It needs a proper PC port and bugcheck.
