I agree 99.9% with no multiplayer for most games directed at single player gamers. Gawd knows RTW might have been sooo much better if the AI of that game had been worked on more than adding a multiplayer game feature to it.
I also look at it this way. I see many that think a game should almost last forever. Well some single player games do, Civilization comes to mind here, Alpha Centauri, Colonization 95 just to name a few that are still great games to this day and mainly because the single player experience is so well done. But, the other thing is if you get MONTHS of gaming pleasure out of the single player experience for $39.99 then you got your moneys worth and shouldn't expect anything more. But, i'm pretty sure with Galciv II just like Galciv I that's going to go way past the 2 months period and well into the future.
Let's face it all games get boring over time, but, still when they are really good later on down the years we can and do go back to them and play them again. I still play some old commodore 64 games "War of the Lance" that was great back then and is still great today. But, when you have games that give you only a few days to a weeks worth of fun and then tossed off the hard-drive never to return, then there's your crappy games without any kind of longevity at all ala Rome Total Crap War. (I still play and love Medieval Total Best War though)
I could live easily without any game ever having a mutliplayer online feature. The only mutliplayer I would ever vote for is PBEM, but, that too I can live without. In todays hectic world and fast paced living, there's just not that kind of time anymore like when I was a teenager and had all the time in the world to do my thing. But, at 13 that thing even then wasn't so much gaming, it was GIRLS!!!! lol Games can get you off, but, not like a GIRL CAN!! hehe
I applaud you Stardock devs for realizing what should be important in your games. And offering up optional mutiplayer in expansions sounds fine by me. I suppose if you can afford it then do it at your liesure. I bought your first game without question and I'm usually very picky about what games I will buy and even waiting until they are bargain bin prices of less than $20, but, I preordered this game just like you were my brother who would NEVER LET ME DOWN! heh
