I've been playing Divinity Original Sin II with a buddy. I was pretty hesitant to try it out cuz I haven't played turn based games before, but I'm really enjoying this one!
I've also been not so patient playing Tears of the Kingdom. I'm admittedly a Zelda fanboy and I don't buy many games on launch so I let myself cheat this one time. I'm enjoying it so far, but there's just so much to do that it's overwhelming sometimes.
I haven't played Elden Ring so I can't speak much to that comparison. The world is huge though, and the enemies are a bit more clever and complex compared to BotW. Certainly not as punishing as Elden Ring, but definitely more challenging than BotW.
You should definitely give DOS2 a go! The story is pretty cool, there are lots of mods you can add if you play on PC, and the combat feels very well balanced.
To be veeeery honest, Elden Ring is actually Dark Souls but Zelda. One game learned a lot from the other, and they're both great. The way I understand it, TOTK is expanded from BOTW and makes it even more of a physics engine game, with people engineering their contraptions (usually to torture the poor Koroks lol)
This is probably fair. Just watching people play it some if the details struck me a weirdly similar. Like starting in a location where a big enemy is riding around on horseback. Having large above and underground worlds.
