As I mentioned elsewhere, better to release a product that has the necessary features to start having an income and then add extra features vs releasing a product full of extra features at a much later date and have to troubleshoot everything at once.
Heck, how many Steam users actually care about cards, achievements, reviews and so on? To me it's Steam that's full of useless stuff that's only there to keep people addicted to the platform and to suck money from whales, there's a reason why they now have the list of suggestions to get you to add games to your wishlist, they can create a profile and adjust the front page to your taste so you spend more money! Super ethical isn't it?
