I hope at least some of the Devs are reading these boards.
You know what I would throw my money after?
A Civ4 reprogrammed to take fully advantage of 64bit, changed siege (and later ships) to do a prober range attack (instead of the stupid suicide sieges), and a working (AI understands) max 25 UPT. Lastly the obvious bugs should be fixed (K-Mod'ish). Thats all it takes to make a super game imho.
Of course I wouldn't mind if they picked one or two features from my VIP mod, but honestly I wouldn't mind creating a new mod on top of the above changes
edit : oh, and a better AI experience with more diplomatic options, such as Unions.
I hate to be a pessimist here, but I very much doubt that the devs are looking much at civ 4 forum. Just take a look at Civ 5, Civ BE, Civ Online and Civ World.
Its almost 10 years since Civ 4 was released, and we civ IV'ers are not the market anymore. I guess the only way forward is a Kickstarter campaign
... and then Firaxis announced a new IP instead, Starships.
While it's a smaller release it pretty much kills my hopes of seeing a Civ6 this year.
Panzer General took place on areas of land the size of a small county, like in Normandy or a tiny section of a front. It was also a limited, tactical excersise.1UPT is not bad for a game per se, it just makes the game more tactical and less strategical. Advanced Wars (for Gameboy) and the early Panzer General series are all excellent games with 1UPT.
Making a good AI might be difficult though.
If they keep 1UPT then I will not be interested in Civ6. Most Civ5 problems come from that. I understand they will not go back to SoD but maybe they can come up with something in the middle, like a limit of 12 units per tile or something like that.
I got betrayed and painstakingly scarred for life after pre ordering Civ V.
