>S tier(either balanced around solo runs or it's more optimal than party runs):
NWN1, DoS2, Fallout 4,3,NW, Necromancer's Tale, Age of Decadence, Colony Ship, BG3, Anything Phyrahna Bites, Arcanum, Tyranny, PoE 2
>A(Solo is alright but game fucks you up slightly with skillchecks/peacful skills that you can only level with a party or some similar minor filter)
BG1 and 2(If you play Mage or Assassin - move it into S tier), NWN2, Dragon Age Origins, PoE 1
>B(It's passible but requires extreme comprehension of what game will throw at you at any given point)
Kotor 1 and 2, Shadowruns
>C(Developer actively nerfs anything that allows such approach or it's straight away impossible without modding)
Icewindales, Wotr(lt's possible without mods but you'll be pressing F9 alot), Kingmaker, Rogue Trader(Only one build can do this, which will probably be nerfed next major patch), Wasteland 2 and 3, DoS1
