(But it’s also heavily on sale right now, for $15 - https://store.steampowered.com/app/526870/Satisfactory/)
Personally, I don’t mind at all. For one I bought it at $30, but also I have 2,000 hours logged. Per hour that’s a cost of $0.02 per hour (at the new price) if I had bought it at $40. I’m all for calling out studios like ubisoft for being greedy, but coffee stain has done a very fair job with Satisfactory IMO, and they very well deserve $10 more for the game.
That being said, go pick it up now for $15
The costs of updates and bug fixes, ie maintenance, aren’t equivalent to building the game from the ground up.
