One needs to note that Solasta is in an almost finished state. Full release is estimated to be sometime in May or June. In fact, there’s a sale right now that’s ending at the end of the month for $28 USD. After that, there will be a price increase from the EA price of $35 to $40 USD in anticipation of the full launch (part of the explanation was that Steam won’t allow discounts within 30 days of each other, and there is assumed to be a launch discount).

That said, BG3’s UI only makes sense when you consider that the framework is based on DOS2’s UI. They’ll probably overhaul it at some point, but I wouldn’t hold my breath as long as the more fanatical portion of the community merely tolerates it.
