Just thought I'd start a funny thread of things that irk you about the game that aren't exactly important. For instance, this isn't about how the AI is horrible at war, or about how bad Japan's UU is, but little nonsensical things that just make you go
GENERIC versus SPECIFIC NATIONAL WONDERS
Ok. I'm going to build a NATIONAL COLLEGE and a NATIONAL EPIC, yet I'm also going to build an EAST INDIA COMPANY and CIRCUS MAXIMUS. The first two are generic names; the second two are specific. This drives me crazy. For instance, there's only 1 Circus Maximus in the world (in Rome), so how can it be a Nat'l Wonder? Just make them all generic for consistency's sake!
ONE SKIN SHADE FOR ALL
Who are those Caucasian Swiss spearmen about to invade me? Oh, it's just Shaka's all-white Zulu army. What's that strange white knight about to attack? Oh, it's just Pachacuti's all-white Incan army. The game needs diversity by default. I know there's several mods out there, but nothing makes me roll my eyes more than the lack of respect for the different nations of the world. You'd think the 5th iteration of CIV would get it right?
RANDOM UNIT MOVEMENT BUGS THAT MAKE NO SENSE
Ever had one of those battles where you take down an archer with your warriors, where one of the warriors charges in WAY AFTER after the battle ended? Or my favorite, a single soldier that spins in a hundred directions after moving to a new spot, keeping the game from going on for about 10 seconds. So bizarre!
