I'd agree that "it gets better later" isn't a good way to promote a game, but I dunno that a game has to be good (or at least at its best) from the start. Totally understandable if people don't want to, or can't invest the time into something that doesn't grip them right away, but at least for me a slow start can be really nice, especially when a game ends up unfolding in unexpected ways later on. I can enjoy that kind of pacing, and sometimes it's rewarding to have something start off kind of painful for one reason or another and become something much greater. At least personally I think a "weak start" can end up making the full experience better overall, as it's kind of a part of the journey.

But of course, if you're not enjoying it and you don't want to continue and you want to refund it... That's totally reasonable! A game that's a slow burn is probably a much harder sell and not going to appeal to as broad of an audience, and I think that's okay.
