I picked up Phoenix Point because I was feeling that XCOM itch and knew if it wasn't this I would start a Long War game of XCOM2 which would probably take 2 years to finish if I did at all.
Far Cry 5 is $6 and though I'm not particularly tempted I've heard good things.
Mad Max is $2 and if you haven't played it I would say it most certainly a bargain at that price. It is fairly boilerplate open world where you take towers and bases to gather resources for upgrades and eventually unlock tougher and tougher zones. The vehicle combat is really the standout and your car is the star of the show. Just tearing around the desert is fun in itself. Taking caravans is particularly cinematic and satisfying to eventually bag one that you just weren't quite able to before your latest upgrade. Unfortunately the base assault and dismounted fighting is pretty forgettable with batman arkham-style auto-target with quicktime blocking that doesn't change very much as you unlock new abilities. My 2nd favorite open world game after shadow of mordor/war.
If you like a fantasy setting, I'm a big fan of Endless Legend, which is the earlier project from Amplitude, who went on to make Humankind. The base game is also half the price of Humankind right now.
Also, I saw they recently parted ways (i.e. got kicked out, probably) with Sega, and are independent again, which could be good.
Thanks.
I don't know much about it, but I used to watch the Armchair Admirals of the Yogscast play Civ6 and constantly complain that it wasn't Endless Legend
Word of warning. Endless Legend is a really good 4X overall, but its famous for how horrible its combat is. Its over complicated and never satisfying. If I remember right (its been a long time) you can mostly auto-resolve it and not get involved, but that leaves you at a permanent mercy of the AI judge.
But its a testament to how good it is otherwise that people still love it despite such a huge hole in it.
