Solasta is an incredibly faithful recreation of the 5th edition rule set. And I absolutely love it. I've played the main campaign, all the DLC, and a fan made recreation of the temple of elemental evil.
The rule implementation is fairly strict, especially when compared with BG3. Can't be casting somatic component spells with something in your off hand. Your wizard spell book is something that you can accidentally sell (oops). Need to attune those magic items. But I find it all pretty fun and I felt like I actually learned more of the D&D rules.
The cutscenes and dialogue animations are... actually comically bad. But I like the idea behind the way scenes work. Basically you set your character's personality at the start of the game and then they automatically speak according to that. Some of dialogue is hilarious. Some of it is even internally hilarious.
But what really shines are the encounters and campaign design. The encounters are all very fun and well designed, there's a fair amount of verticality and environment interaction. Each encounter feels like it could plausibly be part of an an actual tabletop adventure. And the overall story also feels like something that your friend would come up for his homebrew world. It lacks the style and polish of BG3 but makes up for it with authenticity and heart.

Solasta is the closest I've ever felt to playing dungeons and dragons in a video game and I would highly recommend checking out the base game at least.
I swear I am not kidding about this. The Ikea Markus chair is my favorite office chair. I lock the back upright and the lumbar support perfectly contours to my back. I do use an extra memory foam cushion on it to make it a bit softer. Every fancy gaming chair or office chair I tried has felt worse on my back than this chair. The racing style gaming chairs are all too straight and the fancy herman miller chairs are too curved. The Ikea one is just right. I had one for almost 10 years and then the fabric started to wear away so I bought another one and it is also perfect. Try it out before spending $1000 on a chair.
Try Everspace. It's a roguelike space shooter. Controls feel very free and intuitive. There's also a sequel that's out now that's more of an open world space RPG (same shooting mechanics but not a roguelike). But you can try the first game for only 4 dollars and see if you like the combat.
