Oh, good bump @BTripz.
I've been in the land of expansions recently. X-COM 2 : War of the Chosen came down in price a few weeks ago, so I've had a wee go on that.
What's really taken the time is Civilization IV's new expansion, which is a lot deeper than the game it overhauls. Brand new is something called an Era Score, counted up at the end of each age. Civs get Era points depending on how many firsts they manage. Golden Ages trigger for top performers. Dark Ages loom for the little Lebowski urban under-achievers ( and not very proud of them are all of we ).
Moaning bastards will complain that "it should have been like that from the start", and while I'd have a measure of sympathy with that (Vanilla Civ 6 is pared down in complexity compared to many of the others), I had something like 200 hours on that thing before this expansion. It was clearly good enough.
My eldest daughter is a big fan of this too, so sent her a copy. Got an "omg. you're amazing." and a heart emoji. Worth £25 :D
