@Rvil Plum:
I admire your optimism in expecting a good future civ game. However, after the desaster of civ 5 my hopes are very slim. In fact, it's not just civ 5, it's the general direction the franchise has taken over the years which you mention yourself, with games like Colonization, Civ Rev and Civ Facebook. And I've heard that civ 6 is supposed to continue the trend towards "accessability". At this time these are just vague rumors of course and may mean nothing, but in the last years there has been simply no evidence indicating that the current trend will be halted, let alone reversed.
Maybe I don't understand this Kickstarter thing you mention correctly, but it definitely is not the gamer's responsibility to throw in money to Firaxis for a better civ game. This would be true if the company hadn't produced an epic fail, and it is a lot more true after the company's current employees have proven to be incompetent and the direction of the series geared towards simplicity. I for one have no trust left at all in Firaxis, and it is their responsibility to change this. If they prove the pessimists like me wrong by producing a really epic civ 6, I will change my opinon. But once again, I wouldn't count on that happening.
Now on the positive side, the gap that has been created by turning civ into a mainstream casual wargame has already been filled. Despite the trend among most companies towards accessability and dumbing down of their games, there is still a big market left for the 30+ generation or I should better say for people who enjoy deep complex games which require thought and meaningful decisions rather than adrenaline producing clickfest games. Paradox Interactive has filled the gap and if you don't know their games I suggest you check them out. The ones I am familiar with are Europa Universalis 3 and Crusader Kings 2 which are both absolutely excellent and incredibly complex (in a good way). Their other games are similar from what I've read.
Sure, I also miss civilization occasionally, having spent 10.000s of hours with the different versions over the last 20 years. But I also miss playing ultima 6 and 7, battle isle, silent service, betrayal at krondor and even a game like Dragon Wars from 1988. Time changes and we should allow ourselves to adapt to new games. In the RPG genre, Skyrim is a absolutely astounding game, especially when well-modded (and the mod community is simply awesome). Strategy-wise we have the Paradox games. We definitely have alternatives. They may not bring back the magic of Ultima 6 or Civ 2 (or 4, for that matter), but that, I guess, is just the flow of time.
