Going back to Civ5 again as a result of this thread. I read Sulla's criticisms of it, and they're valid, but I think he plays Civ games for different reasons than I do. He's a systems and ultra-high difficulty guy, whereas I prefer immersion and roleplay, and Civ5 kicks Civ6's ass in that respect because you don't have to play optimally to beat the AI, you can do wacky builds and have gimmick strategies - today I will be play mercantile empire, tomorrow I will play an all-conquering horse horde, I can play tall, I can play wide, whatever. Civ6 punishes you for specialising and there'a a very clear optimal way to play - you have 7 cities, each with a different advisor and specialising in something else. The systems lead to absurd things, like building military units you don't need to avoid penalties to researching key techs. It's a board game, it's all systems and optimal play and all the Civs feel the same to play (except the ludicrously overpowered Aztecs). It's clearly a very good game if you're Sulla and play it only for the challenge, but it's not pretending to make you feel like you're running a real empire any more. Ripping Civs out of the base Civ5 and selling them back to you as DLC pissed me off too.
I just got Before We Leave on sale. Looks like a lot of fun, a hybrid 4x/Citybuilder without combat, just production chains, trade and diplomacy. I like slow-paced, chill games like the early Settlers games so this might scratch my itch.
I'd also recommend Songs of Syx. It's an early access game that's made by just one dude. It's a weird citybuilder/4x/Total War game where you build a city state then raise armies to conquer your neighbours and make them hand over their resources to you. Ngl, it's the ugliest game I've ever played and has a horrible interface, but the depth of the mechanics is incredible, at least in the city-building mode. The strategic mode is a bit light on things to do and the battles are basic AF (he only just introduced ranged units in the last update) but future updates are due to work on the combat.
