I only estimate price per hours. Larian type game for me is good. But I only can be play it once. I do not have it in me to replay it after one completition.Yes, DLC model is evil, and it's a tragedy that the market equilibrium is set where it's set.
But I think most people simply don't factor it, when estimating their excitement for the game. I certainly don't. Even though, Larian rightfully deserve massive praise for the integrity of releasing a full experience for a single price, sales practices are a separate thing from the game itself.
The best way would be to buy the heavily discounted complete edition several years later.
I estimate this game to be one of my cheapest games per hour (civ 6 might beat this still) and initial price is quite irrelevant or model they sell it in.
