I'm a 40ish year old dude and I prefer 2d over 3d usually and wanted to recommend a couple of games;
Brigador (Syndicate with mechs, moddable)

Starsector (2d Elite with 4X properties, lots of mods available, overhauls etc)
Bonus game; Distant Worlds Universe, a great 4X game (good mod set)

Additional: Wayward Terran Frontier

Greetings comrades. I'm currently on the road with my face mask searching for a bread line with wifi that isn't actively burning to the ground or experiencing rolling blackouts. I found a nice place that allowed me to stay for a while even though my presence increases their risk of death from the common cold by as much as 0.004% and I thought, why not lets talk some more about development progress and hopefully I don't get cancelled before I can finish this patch.
They turned all the livestock gay, so they stopped breeding and all died out?
That's rather oversimplifying (as usual for DF), but yep.
(To elaborate a bit more... on average 75% of creatures were interested in the opposite sex, and both had to be interested to breed, and on top of that some creatures were sterile, and on top of that some creatures were uninterested in marriage (which was a prereq for breeding). Oh, and it was bugged such that setting it to 100% anything would cause it to silently revert to the default orientation settings.)
