Those days never left. There's been a ton of TBS games released throughout the years, some of them very very good. It's my most played genre by far.

Endless legend, XCom 2, Fallen Enchantress, Age of Wonders 3, Age of Wonders: Planetfall, battletech, some tbs rpgs like divinity original sin 2, the total war series is a hybrid RTS/TBS genre, card games, tower defense games, and auto battlers.
