Credit where credit is due: MEGA CRPG RECOMMENDATION LIST. Tasty comments full of people disagreeing on the OP's categorization. Seems to have deleted their account, so no u/ I can direct you to. I left all the recommendations and categorization alone, but took out some of the color commentary (which to some might just be blandifying it, lol).

"Where do I start?" mainstream recommendations

These CRPGs tend to get recommended the most by others who are newer to CRPGs themselves and very likely started just within the last few years.

• Divinity: Original Sin 2
• Pathfinder: Kingmaker
• Pathfinder: Wrath of the Righteous
• Pillars of Eternity
• Pillars of Eternity II: Deadfire
• Wasteland 3

"I'm looking for a good CRPG" middle-of-the-road recommendations

The person asking this question likely has some CRPG experience. The games that I listed here are great, but came about before the big CRPG renaissance that the mainstream gamer is familiar with. They're extremely common to most people who've been playing CRPGs for years, and will very likely tug some nostalgia heartstrings despite the fact that the some mainstream gamers may feel confused or even put off by some of the older design principles. These recommendations tend to be for the person playing catch-up, working backwards from modern releases to the older stuff that CRPG veterans would still consider to be mainstream.

• Dragon Age: Origins
• Star Wars: Knights of the Old Republic
• Star Wars Knights of the Old Republic II: The Sith Lords
• Vampire: The Masquerade- Bloodlines
• Gothic series
• The Elder Scrolls III: Morrowind
• The Elder Scrolls IV: Oblivion
• Shadowrun series

​# "My dad played it, but is it any good?" forgotten recommendations

These CRPGs haven't actually been forgotten, of course. They're just not spoken of regularly when compared to the modern recommendations, but a lot of long-time CRPG fans have played them and can recite fine details about their experiences of them. They were likely extremely popular at one point, maybe even to the point of being considered legendary, but have been drowned out by mainstream recommendations. In this territory, the mainstream gamer can often be seen twitching uncomfortably at some dated design principles and will shift in their seats with impatience due to the lack of quality of life options or untraditional design choices.

• Baldur's Gate
• Baldur's Gate II: Shadows of Amn
• Neverwinter Nights
• Neverwinter Nights 2
• Icewind Dale

"I think I've heard of that before!" not the first to come to mind recommendations

CRPGs that maybe some people have heard in passing, or they know a guy who knows a guy whose uncle played it at some point. These are the recommendations that are a point of pride for the people who mention them, because they know that not many people have played them, or possibly have even heard of them. Some of these also tend to have a bit of a niche following or aren't quite as popular as other entries in their series. Not everyone will love these, but the ones that do REALLY love them.

Some of these games are difficult to even find a single archived mention on a website, and if you were a completionist collector and wanted a physical copy of some of these, you'd be hard-pressed to find them.
