Everyone says AI but I've gotta say it too.

I would like to see a TW set in the modern era like WWI or WWII.

Also, I'm surprised so few others mention this (or there's not a mod for it), but I'd like to see blood, severed arms, heads, screams of agony and such. They could have a toggle between clean and bloody. Though I guess this is wishful thinking, since I'm sure they don't want an M rating which is understandable. Still I'm disturbed by the Disney-fication of RTW. They don't even have the death rattles that soldiers had in MTW when they die.

I'd like to see characters that drag the wounded out of the melee and soldiers who are wounded limp out or crawl out.

The return of prisoners and ransoms.
