Good for them. Larian does not need D&D at this point. All the people who liked BG3 aren’t going to shun a new Larian game just because it doesn’t use a D&D setting. Quite the opposite, in fact. Them hyping up their own stuff can only help them keep people interested.
Meanwhile, Wizards can’t generate hype o matter what they do, because they are scared into stasis from the knowledge that they are out of ideas. Heck, a lot of the changes Larian made to the ruleset are things that the people at WotC should have made many years ago. It is very telling that those same people can’t help mentioning the game when they are trying to hype up their new version of 5E. A version that is scared to change anything except tiny details via a focus tested surveys and looks basically identical to the game they delivered ten years ago.
BAR is really good and also free to play. If you want a sweaty RTS to play, here it is!
