I recognize all those games except Euphoria, I really like Aurelia although it's a bit light on content, and WaL has a great setting and cool art but feels stiff and unfortunately isn't animated IIRC. The other ones I could take or leave, even as a huge Avatar fan lol
I dont know, Summertime Saga is just the best 2D game out there for me. It's not perfect but it has a vibe that makes it fun to make progress around the sandbox, and I think the art and characters, while not perfect, are great. There's also a lot of content and its animated for the most part.
The games from Siren's Domain are kind of in the same ballpark, and Demon Deals, while not for everyone because of the exaggerated bodies, captures the same feel.
Sorry for yapping lmao
