No idea what to recommend to you, I'm not an RPG fan
Try out Grim Dawn, Titan's Quest and I hear torchlight is good too.
Keep an eye out for Bannerlord and Kingdom Come dilverance, there was also some early access title. Otherwise I don't know.
I think you're shit out of luck if you're looking for good recent single player TPSs. Try out Strong Hold and the rest of the C&C games if you have not already

Sky Rogue's looking pretty rad, otherwise you've got nothing besides emulation. Give Ace Combat Zero a shot, in my opinion it's the best.
If you're looking to get into total war play Rome, Medieval 2 and Shogun 2. If Empire looks kind of interesting to you Cossacks 2 is kind of similar and is pretty rad.
Here's what I can recommend:
Great first person combat. Messiah might be the best first person combat game ever made.
Alien purging goodness. I recommend against the firaxis ones but if you must play them give The Long War mod a shot, and be sure to try and look up how to mod out some of the more bullshit aspects of it and you'll have a blast.
fun Space dogfighting
No idea on the remastered games, but HW1 and 2 are great games. I hear deserts of whatever isn't too similar to either game but is fun irregardless.
Great post apocalyptic rpgs
Great FPSs. FEAR is more tacticool and is a bit hindered by the horror setting but is fucking great(you're a pussy if you play with reflex), Painkiller and Serious Sam are pretty much wave killing vidya with lots of fun weaponry and secrets, Lovely Planet is a speed runner but is a very fun one at that
Great hack n slash games. In rune you could pretty much dismember someone and then beat them to death with their own arm. Serverance is often referred to as proto dark souls but I just don't see it, but it's an amazing game regardless
four man dungeon crawlers. Grimrock is pretty rad even though I haven't played it to completion
Turn based tactics similar to x-com. Invisible Inc is more stealth based, Silent Storm is kind of hard and you need to mod out panzerkleins but is otherwise great and 7.62 high calibre is operator:the game
Stealth vidya
incredibly fast arcade car vidya.
I had a bunch of puzzle games, give me a bit to remember them
