Your biggest problem is going to be the graphic card. Darkest Dungeon isn't resource intensive, but it needs a decent graphics card as the intergrated intel card won't cut it (at least when it was released, I think they may have changed that recently).
Totally works with integrated graphics if you have a decent PC. One of my favorite games to play on my integrated graphics netbook.
I'll vouch for shadow magic, too. Great 4x, not very resource hogging. In large maps late game turns can get sloooooow though.
Some more things:
Hack and Slash:
If you have an itch for hack and slash Torchlight 2 works very well on modern integrated graphics systems
IIRC Victor Vran works but I might be misremembering
Dead Cells works.
Blasphemous works (but Dead Cells is better)
RPGs:
- Old Baldur's gate games, of course. Either the originals or the remastered ones, matters but little.
- I can vouch that at the very least ShadowRun Deadman Switch and Dragonfall will work. Havent tried Hong Kong yet
- Neverwinter Nights 1 works very well. NWN 2 suffers from massive slowdowns
- Neither KOTOR 1 nor 2 play nice with integrated graphics. KOTOR 1 has massive bugs, KOTOR 2 crashes- Haven't tried Darkwood yet but it should work.
Strategy:
- AI War 1 and 2 work
- Mount and Blade Warband works
- Nantucket works
- Infested Planet Works
- Warhammer Gladius (think Civilization-like game in Warhammer) works
-Another XCOM alternative: XENONAUTS. If OpenXCOM isn't your thing you might try this. Then again it's quite similar to OldCOM, might as well stick with OpenXCOM
- As far as NewCOM goes, XCOM2 won't work but XCOM1 on low graphics just might
- Steamworld Heist works
- Big Pharma works (but hard as I tried I was never able to get into it)
On the more abstract side of strategy games: Spacecom and frozensynapse work. So does Reprisal Universe (remake of Populous)
