I second Sierra Lee games being among the better ones.
Just be aware that Desecration of Wings (I think) and Last Sovereign (definitely) were developed/written in "Patreon-style" - meaning a: the game(s - mainly TLS) nowadays are HUGE/LONG and b: an amount was written/developed and published, with mainly early-on patreons/players in mind. Players then had 2 months or more to play with that before the next batch arrived. So the gameplay is often: finding out how to best solve this or that situation, by reloading and replaying several times. And it is mostly (very) well-done for this play-style.
For example me playing TLS while longterm offline, I tried the "Ardford Summit" situation about 6 times (that's >20hours net, being totally convinced that funding the Sanitation Mages (yes. lol) with so much money would give me sth. directly, like access to sewer dungeons (more XP!), to then maybe plunder the war vaults or sth. ... yeah, well, no) and only then, on the 6th replay I accidentally found out how I can have the summit decide things the way I want 100%. This fired me up and had even more replays, but even with 12 or so replays I never found out myself that I could have gotten the Vinario Deeds for even less than those *spoiler* €€ ...
playing Des.of.Wings/TLS in one go ... soon can get tiring, noone can pay that much attention to details all that time, be enthusiastic about "yay!, yet another complicated puzzle/mess of a situation / puzzle-battle/ some-such."
sorry, got carried away TLDR: Do not try to play Sierra Lee games/ TLS in one go* - take (many) breaks and it is good .
If you enjoy reloading-and-replaying-parts-to-get-better-results - then it is even better. else use of a walkthrough may be needed.
Also: TLS has the best orcs ever, those alone make it worth playing/reading.
* (well, Ouroboros is OK to be played in one rush, I think)
