Hmm..
Civ has sucked so many hours away from my life - most of that was C2/C3 though. C6 was pretty underwhelming for me, although I'm due to play through another game or two of it - haven't fired it up for years.
I have a similar experience.
I was really into the original Civilization and Colonization back in the DOS days. I skipped 2 and 3 though. (I was in academic hell in 1996 when 2 came out, and when 3 came out in 2001 I was in my Counter-Strike addicted phase)
I got back into it with 4, which I put a ton of hours into, most of them outside of Steam, so I have no idea how many hours I actually spent in that game.
When I got into 4, the final expansion (Beyond the Sword) had already been launched. It was pretty awesome.
I found 5 to be a disappointment when it first launched, but it got better with each expansion until with Gods and Kings expansion it was really quite good.
The same thing repeated itself with 6. The initial release was a disappointment, but by the time the final expansion (Gathering Storm) came out it was quite enjoyable as well.
I'm going to go out on a limb and suggest that at least since 4, this is how Civilization goes:
- Initial Release: Meh. Not complex enough.
- First expansion: Adds some complexity and balance, fixes some annoying bugs and makes it more interesting.
- Second expansion: Adds more complexity and balance and turns it anywhere from good to great.
Rinse and repeat.
Since there are usually 2 years between initial game launch and first expansion, and one more year between first expansion and second expansion, if history is any guide, Civ 7 will be in its best final form by 2028...
Even with the expansions making the later games better and better, my time spent in game has dramatically gone down with each release, in part because I am no longer a kid with near unlimited play time, but also in part due to the fact that it can't help but feel like more of the same.
The tweaks they have made to make things different and interesting (hexes instead of squares in Civ5, city districts in Civ6, etc) have simultaneously been mildly annoying (at least at first until I got used to them) and also not been enough to feel like there was something new there.
One thing that really bothered me with 6 was the art style. They took a more serious looking style in 5 (and previous releases, albeit limited by the graphics at the time) and turned it cartoonish in 6. That bothered me a lot. I haven't watched the game previews of 7 yet, but I
really hope they reverse that. I have a sneaky suspicion they haven't though
