You can’t really find out of you’ll get good enough to enjoy a soulslike without buying one and playing it for longer than the two hour refund period. For other products, you usually have something you can do about it or some way to try it first. You don’t need to buy a kayak to find out you don’t like kayaking as you can go for a kayaking lesson first and use the venue’s equipment. It’s understandable that people who hit a wall and can never get any enjoyment from a soulslike will be upset that it cost them just as much to find that out as it costs someone who’ll compete the game and have a great time.
Maybe it’s enough to just do the refund window based on progression rather than time.
