Not necessarily. It's not just the price of the game (incl. various editions) but also the associated merchandise, if a game has any. A lot of revenue can be generated through sales of all those coffee mugs etc. Though I'd say games are behind other fictional works like movies in this regard.
That's certainly true. I'm also not including other intangibles such as: the benefit game X has for the company, leading more people to buy their next game Y, and I'm sure a few other effects. But again, all of these things still need to be divided by the cost to make the base game.
I feel like crpgs in particular don't sell that much merch, but I wouldn't be surprised if vastly more BG3 merch was sold compared to WotR, even taking into account their budgets.
