For the games on my list, the following have save anywhere:
* Ultima 5 and onward (4 only allows overworld saves)
* Wizardry 4 and 6-8 (4 not on GOG, 4 forces you back to the title screen and enemies respawn on reload)
* Infinity Engine games (except that the game might not let you save if it thinks enemies are nearby; in BG2 I had to rewatch the cutscene between chapters 3 and 4 because of this)
* Both Pathfinder games
* Bard's Tale remastered trilogy (also original 3 and some versions of 2)
* Elminage Gothic (reloading in the dungeon has a minor time penalty, which can eventually age your characters)
* Saviors of Sapphire Wings
* Ys 1 and 2 (also Ys 3, but not on GOG)
* Civilization games and similar
Save only at certain points:
* Ultima 4 allows saving only on the overworld
* Stranger of Sword City Revisited
* Timespinner and Bloodstained (but they're still manual saves, unlike in something like Hollow Knight, and to me that's a significant difference)
Perhaps I could mention that the Elder Scrolls games have manual save anywhere. (In fact, because of bugs, it's best to save often and in multiple slots when playing one of these games; probably a good idea for WRPGs in general, for the reasons I mentioned in the topic where I explained why WRPGs are buggier than JRPGs.)
Also, The Alliance Alive HD Remastered has an interesting approach: You can manually save anywhere, but you only get one slot. (Note that this save doesn't have any other catches; you can reload from it as many times as you want.) However, you also get to save at the inn, and you have plenty of inn save slots.
Vendor-Lazarus: I saw you mention google docs not working (good, we should distance ourselves from evil monopoly google), so here's an alternative:

I'd be interested in knowing
where the saves are located, since having them in the game folder fell out of practice a while ago. It would also be good to know what kind of saves a game has.
Deletes save: roguelike
one save slot or more
checkpoints
etc.
It's not a linear progression.
Case in point:
* Nethack effectively lets you save anywhere, but the save is effectively deleted on reload or death. (This is typical for roguelikes.)
* Final Fantasy 3 (Famicom) only lets you save in certain spots, but you can reload the save as much as you want. This becomes a major issue in the final dungeon, due to the fact that the only place you can save is relatively early in the compound dungeon (after the 1st of 4 parts), and there are a total of 6 bosses you need to kill after the point of no return (plus 1 fight you're supposed to lose).
(There's also a difference between automatic checkpoint saving and manual save point saving.)
Forgot to mention:
* Ys 6, Ys Oath in Felghana, and Ys Origin only allow saving in specific spots. (Note that I am not familiar with any of the later Ys games and how they handle saving.)
