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.
Xenonauts is a better XCOM experience than Phoenix Point. The latter has a lot of strange design decisions that were compounded by all the DLC they added.
Phoenix Point also did one of the biggest 'fuck yous' to gamers in history.
They, to my knowledge, handled Epic exclusivity the worst of anyone, ever, anywhere. Lied to everyone, didn't honor it, told their backers to get lost, basically.
That's hard to do, because there have been so many legitimately awful handlings of it.
Its almost impressive how many companies managed to find a unique way to destroy their own games by taking Epic's money and then making sure to burn it on bad PR.
"You [the backers, who funded us to build this game] could all refund, and we'd be fine." - Those fuckers, paraphrased.
"Also, we never promised Steam keys [they did.]" Same fuckers, paraphrased.
Steam exclusivity isn't much better. At least at the start of Epics exclusivity lots of games were DRM free.
Phoenix point is definitely... Something. I tried it when it first came out, so I have no idea about the dlcs, but it felt really awkward to me. Power scaling felt off in general, some of the mechanics didn't really click (at least for me, some people might enjoy them), and the setting felt... Meh. Could have been cooler, but didnt end up being that meaningful to me.
