I think Civilization should stay with square tiles, right angles are superior and easier to understand than wavy hexagon lines. Units should be able to stack on the same tile, and be able to be promoted when they gain experience in combat. Stacks of doom should be prevented by having siege units like catapults do collateral damage to multiple units in an enemy stack. They should have religion, where you can create missionaries and spread the religion to other cities, and AIs should hate you if you have an infidel religion like in real life. It'd be cool if they had espionage too where you can make spies and poison the enemy's water supply and stuff, and you should be able to invest gold and get espionage points to spend against the enemy. You should be able to found cities with settlers and create improvements on land with workers. Some possible improvements could be mines, farms, windmills, etc. You should also be able to make towns that give you commerce, that you decide whether it goes into science gold culture or espionage. In diplomacy you should be able to have open border agreements and trade resources to each other and techs. You should definitely be able to trade techs. I also think it'd be awesome if they had Great People that did different things, and you could use them to start Golden Ages because that's realistic. Anyway thats my vision of Civilization 5 and if they implement my ideas it will be a great game
Point taken and sarcasm noted.
However, I think there is a fundamental difference of opinion on these boards on what people are looking for out of CIV 5. Some (and I fall solidly in this camp) are looking for a updated version of CIV 4 (much like the move from CIV 3 to CIV 4), while others are looking for (or willing to accept) a largely new game that plays totally different than CIV 4. While nobody knows what the final version will look like, so far, I think the first group is pretty unhappy with what has come out, while the second group is hearing what they like.
Personally, I think CIV 4 was one of the best games ever made, and built on its predecessors to get there. Even so, there are certain areas of the game that still lagged behind the others and either needed tweaking or major revisions. I would list religion, diplomacy, naval/land unit interactions and espionage as examples of these categories. My ideal CIV 5 would be a refinement of CIV 4 that addresses these areas and builds on them. Updated graphics and all the other bells and whistles would be nice too, but not nearly as important as these refinements. However, CIV 5 could look largely the same and play largely the same, and I would be perfectly happy if these systems were fixed and updated.
My current impression, however, is that CIV 5 has elected to simply remove some of these areas (a major step back) and sharply change gameplay in areas that I don't think were broken (one unit per tile and ranged combat, as an example). To me, these changes are either steps back, or a "step to the side" in the direction of an entirely new game, rather than a step forward. My concern is that CIV 5 will be a totally different game, instead of an improvement building on the previous ones, and will lose what has made the series special to me even if it does turn out to be a great game in its own right.
By the way, I want to avoid being totally negative and say that I am excited about some of the improvements we are hearing about. As a couple examples - Hex tiles are a nice touch that open up a lot of possibilities for game play, and it sounds like the diplomacy end of things is getting many of the revisions I've hoped for. I'm sure there will be a hundred other small improvements that I'm not even thinking of that I will like in the final version of the game. At this point, however, I'm very on the fence as to whether these items will make up for what seems to have been lost in getting there.
