Well, here are some suggestions. I’m trying to think of games that don’t have much if any crossover with current consoles.
PICK ONE FROM EACH CATEGORY ONLY. I’m not responsible for your health and wellbeing if you don’t!
WHAT’S OLD IS NEW AGAIN RPGs
Shadowrun (any game) - Straightfoward old fashioned isometric RPGing that’s not too demanding in time or effort. Dragonfall is probably the best one, though i like Hong Kong too. Guns, swords, magic and cyberpunk and you can’t go too wrong.
Warlock of Firetop Mountain - 80s gamebook becomes 3D isometric text adventure.
Sorcery! 1-4 - 80s gamebook becomes 2d+ isometric text adventure.
TOO CLEVER FOR THEIR OWN GOOD
Paper’s Please - Pasport checking on the clock to feed your family. Every mistake costs your family. Glory to Arztoka.
Stanley Parable - The cake is a lie, the game.
Factorio or SpaceChem - Design the production supply chains of your dreams.
YOU POINT, YOU SHOOT
Can’t think of any not on consoles, tbh.
METROIDTASTIC
Because you like these games for some reason.
Cuphead - 1930s technicolor animation meets wiz-bang soundtrack meets metrodvania meets Dark Souls.
Spelunky - The darling game all the cool kids liked for 6 months. Randomized levels.
Broforce - Everyone loves this but me because I literally cannot figure out how to start a level!
PARADOXIFICATION
You either drop them after a couple hours or play them for a thousand (literally).
Europa Universalis 4 - paint the map your color. Not much interpersonal drama. Lots of guns.
Crusader Kings 2 - paint the map your color. Lots of interpersonal drama. No guns.
Stellaris - paint the galaxy your color. Not much interpersonal drama. Some interspecies drama. Laser guns and genocide.
Cities: Skylines - A better, more boring Sim City. Very Scandinavian.
Surviving Mars - An upbeat ant farm on Mars where the ants are men.
Warlock 2 - Surprisingly not bad for a fantasy Civilization-like made by the B team.
STRATEGERY
Civilization 5 - Anyone who tells you Civ 6 is better is a pod person and can’t be trusted. Anyone who tells you Civ 4 is better may be telling the truth but also hates fun.
Ultimate General: Gettysburg - You don’t have to tell which side you play.
Homeworld: Deserts of Kharak - prequel to Homeworld where the spaceships are sandships.
Dawn of War 2 - The Definitive Warhammer 40k RTS. Like 15 minutes of audio barks per character it’s madness. Also arguably best RTS soundtrack ever.
Age of Wonders 3 - Downtempo fantasy 4X w/ quick tactical combat. Sprawlingly endearing?
Endless Legend / Endless Space 2 - Smart 4X strategy gaming that almost avoids being boring. One for pewpew, the other clangclang. Endless Legend is the more attractive game, but the soundtrack for ES2 is a bit more on point.
INDIEGALAGA
Atom Zombie Smasher - Pixelzombie squash patrol in Argentina?
Dungeon of the Endless - Almost too smart and stylish randomized dungeon romp / tower defense? / narrative-light adventure?
Invisible, Inc - smart stealth action
Infested Planet - Pixelzerg squash patrol.
The Curious Expedition - Pixelpithhelmet explorers of randomly generated Pixeljungles that will sometimes sink into the ocean if you pick up the jade bird. Madness is in the air.
UNCREATIVE ASSEMBLY
Most of the games released post Rome 2 are pretty much the same as each other. Yes, there are differences, but they’re like differences between 80s LA punk bands vs all possible forms of music.
Rome 2 - the most maligned, still getting updates. Honestly it’s fine now.
Attila - My favorite historical title. Raze cities, ramble on as a horde. OMG so many city towers. SO MANY. Be prepared to spend a year of your life fighting every battle manually if you want to save Rome.
Warhammer 1 - The Empire! Bretonnia! Vampire Counts! Chaos! Heros and magic make general units feel right for the first time in a Total War game. Note that the invasion of Chaos is about 10x wimpier and more disappointing than the Huns in Attila.
Warhammer 2 - Pointy ear elf things! Benedict Cumberelf! Lizard things! Skaven will kill kill them all!
Thrones of Bretonnia - Why does this exist? It’s just fine if it’s the only Total War game you have - it might even be good in that case. Compared to everything above it’s weaksauce. But, you might prefer its theme/setting, in which case it’s fine.
