Sid Meier's Civilization Series

I have played all of them except for the new one. Honestly, I'm not a fan of the aesthetics of VI. The graphics look very cartoon-y to me, and a step backwards from Civilization V. Last night I played a game of Civilization V from 6 pm to 3 am. The "one more turn..." syndrome can make the hours seemingly fly by, and make you lose track of time. But I built a really awesome culturally focused civilization with Egypt. Which was really fun for a change, because I usually like to play as war-like civilizations.

In regards to future iterations:

I suppose more immersive game mechanics that better reflect the real life dynamics of geo-politics, and civilization would be awesome.

But other than that, the graphics are a main reason for getting a new version of a game like Civilization. I think my favorite was Civilization IV, after I heavily modded the graphics and the map scripting, to make more realistic terrain. I want to see more photo-realistic graphics, and battle animations. I don't want it to look goofy, with people that have giant feet, and disproportionate anatomy. And Dumb looking buildings, that curve, like it was drawn by a 5 year old.

I like to mod FPS, but I would love to create a turn-based strategy game like civilization.
