Seems weird to me that Solasta has so much invested in getting 5e right but not have multiplayer implemented. Single player D&D just feels odd to me, like you have strayed so far from what D&D is meant to be - can it still be considered D&D at this point?
Aren't BG1&2 (arguably the best D&D video games) considered excellent single-player experiences? There's nothing that requires a D&D game to be multiplayer.
Obviously it'd be incredible if Solasta was multiplayer, and even better if a DM could control monsters directly instead of them acting on their AI. But that's simply too much work for their 12-developer studio. Hopefully Tactical Adventure's next game will include multiplayer.
I agree, I hope they got enough sales and supports to do bigger and better things, like Larian did in the past.
