I would love to see 2Kgames completely give up on Civ 5, and start developing Civ 6.
* When they do this, they would listen to all the feedback on Civ 5, and engage fans during the development of the game.
* Ideally, they would not rush the game out full of bugs with simplistic game-play.
* If 2Kgames wants to make a simplistic Civ game that is more "accessible" to a wider casual gamer audience, start a new Civ brand, making it clear to people that this is different.
* The lead designer, Jon Shafer, should be tarred and feathered. Or, Civ style, he should be sacrificed to "rush" development assuming the Slavery Civic.
I think the many hardcore Civ fans that previously supported the franchise, buying every previous game and expansion are willing to give 2Kgames another chance.
What about Civ 4 though? I would much rather have them redo civ 4 with new graphics and civ 5 style civics(and religion and corporations are still in) that is compatible with former civ 4 mods(civics would need to be reworked a little of course), sort of like what Bungee is doing with the Halo franchise. Maybe they would also include ranged combat and a unit tile limit(something like 5 combat units per tile max, or 2 worker units per each combat unit that isn't present allowed).
Oh, and there would be plasma. Lots of plasma.
