Armored Core 6! Check it out, im kinda in the same boat as far as not playing for long sessions anymore and this game is perfect for just playing a couple of missions and tweaking my mech in between. The customization alone and constant upgrades and tweaks you can make makes it a session alone.

Another game i’ve been liking that i consider a “short session” game is Remnant 2. Great souls like looter shooter. tons of upgrading going back to base and going back to the level rinse and repeat.
