For me, I've been getting into souls-like games. They scratch a similar itch to MH when it comes to skill-based play. There's a new one coming out in a few days called Remnant 2 that looks to be on the less punishing side. Not sure if it's what you're looking for but worth checking out to see if you haven't heard of it.

You might want to give Dauntless a shot. I haven't played it in a while, but it's basically a free monster hunter clone. The graphics weren't up to MH levels, but the combat is solid and the crafting system is pretty fun.

Oh, obviously Wild Hearts if you haven't tried that yet. I don't know if it has crossplay but it's a newer MH clone with some interesting new mechanics. I found it to be just okay but it might scratch the itch for you.
