Thanks for your replies, all!
If it's not too late, I'd like to chime in a little, just add my little 2 cents.
I also, like many others here, feel strongly that the cohesive DLC history we've had with CIV has been very mostly positive, be it R&F and GS for 6 or those for the previous version that, in my mind, greatly enhanced the experience.
Have they been all perfect ? No of course not. But I think that they've all been positive.
NFP, on the other hand, was in my mind an experiment on your part. Partly because of the Covid situation, partly (and I may be wrong here) for trying out a completely different development process from what had been used before, that fits better with the working from home paradigm.
While I'm not AS negative as most people here on the results of that experiment, I also feel that this is NOT what I'm hoping the future holds for the CIV Franchise. And the reasons is exactly as described by most other contributors here:
1) It's not cohesive with the global game at all. They're mostly great to interesting ideas that could've added depth to the game, but in the end they mainly wind up uninteresting because they're either broken or the player gets a LOT better advantage than the AI can.
2) I feel the cycle was too fast for the dev Team, or at least the QA in the dev team. Being from the IT world, I understand how the new dev processes all promise magical automated testing, but the bugs we've seen in NFP mostly seem related to global breaking of ANOTHER system in the game, not the actual system put in place.
As a result, and I'm talking FOR ME only here, I wind up using tech/civic shuffles all the time (this should have been in the original game btw, as a simple yes/no box option at game creation), Secret societies most of the time because I just love owls and Sanguine pact... Still, even here, 50% that I DON'T use....
As for the rest, Heroes and Barbarian clans were fun for a while but I turned them off now, Dramatic ages and Apocalypse I tried once and never returned. Zombies I never even tried it, but hey, that's just me... Monopolies and Corporations was a fantastic idea, unfortunately badly implemented and unuesable because of
a never fixed bug... Still can't get over than one, honestly !
In the end, I'm happy about one and a half of the 8 modes offered, plus ALL the new civs (this must be noted... new interesting civs are important). AND the game wound up pretty bugged after NFP, so I feel it's quite normal that we all feel VERY concerned about the possibility of this pattern repeating itself for CIV 7. I can't think of any way that analysis of the results from NFP could be construed as positive; The game wound up in bad shape because of this, and the only game saver is that we CAN turn them off. I know money speaks, but you guys must also be wary of the fact that many people bought NFP but would NOT buy it again...
My personal opinion is that the CIV franchise magic lies on two pillars: 1) A wide offering of Civs and Leaders that have abilities, strengths and weaknesses that greatly differentiate them from one another and 2) A collection of systems/features that also greatly helps replay value; Distinct maps, tiles features, resources, districts etc...
I sincerely hope that you guys will not stray too far from those two ingredients.
Finally, thanks for being on the lookout for our opinions. Very appreciated. Hope we hear from you soon
