You can actually get away with high prices for games. Just comes down to how much pull a company thinks they got.
Factorio has never been dumped at insane low prices. In fact, the price of the game has gone up I think. There's many weird strategy games I sift through on Steam. These odd games you'd think would be $10. But they maintain it at around $40. And when it goes on sale, it's maybe modestly 30% off, and not 75%. Theire thinking is they got a niche game and if any hardcore gamer wants it, take it or leave it.
I guess MS originally thought OW2 is that kind of game with pricing power. It definitely isnt that kind of game. Or they thought if Mario can do it starting a trend, let's jump on the train too.
Not a smart move.
