Nah. GalCivII is okay, but it’s got some really, really annoying features. I still prefer MoO2 in many respects.
If GalCiv II had multiplayer and a tech tree that wasn’t so lopsided it hurts…
I much prefer Sword of the Stars for my MOO-style fix these days (even if it’s closer to the original MOO than anything else)
Sword of the Stars is my space 4x of choice. It eliminates all the crummy micro from MoO2 and the balance verges upon the scary. The randomized tech tree and well differentiated races add a lot of replay value. I would and do (since I still have a MoO2 CD and it’s no great effort to get it running) choose it over MoO2 any day of the week.
About the only thing I could ask from it in terms of improvements would be a more robust espionage system; The MoO2 system wasn’t super exciting, but it covered the bases in a way that the cobbled on SotS “system” doesn’t. That said though, espionage is a pretty minor part of these games (to say the least.).
