1. Open World RPGs in either 1st or 3rd person perspective (like Skyrim, FO4, Elex). Bonus points for those that include an in depth crafting system and home/base construction, or settlement construction.
2. Party-based RPGs, usually isometric, but occasionally 3rd or 1st person perspective. The strongest ones have in-depth party/companion interactions and personalities. Bonus points for detailed companion questlines and backstories. Such as the Dragon Age, Mass Effect, Baldur's Gate, and Pillars of Eternity games.
3. Action RPGs (ARPGs). From my playing experience they're mostly isometric, like Diablo, Sacred, and Grim Dawn. But they can also be 1st or 3rd person, though I have less experience with those. Kill, loot, level up, and upgrading equipment are the primary goals.
An addendum to the above: Any of the above genres that have the "souls-like", "rogue-like", "MMO", or "online only" tag are immediately ignored.
