I’m not throwing shade at BG3; I’ve also enjoyed it, but something about the sheer amount of options and more widely diverging story paths in Wrath just does it more for me. I also like the art style more, but that’s strictly subjective and I accept that.
To a lesser and more personal extent, I despise Wizards of the Coast/Hasbro and their recurring attempts to monopolize and bully third party game developers and players alike and I don’t like to even indirectly trickle money their way compared to Paizo. Yes yes, no ethical consumption and all that, but Paizo’s way less fucked up with both distributing game materials and open licensing agreements.

That’s all I had to say. If you’ve already finished BG3 or it wasn’t quite to your liking and you’d like an alternative, give Wrath a try. 
Exactly! I guess you can do an evil run in BG3 if you’re okay with losing parts of the game in return for some additional dialogue. The combat system of D&D 5e also doesn’t really entice me to try another playthrough as a warlock or something, especially as you can just respec everyone whenever, and let’s not even mention the romances. But the mythic paths in WotR really do make an impact on the game, especially mechanically, when it comes to your main character.
