It seems like there's a modern definition of scam, especially with gamers, which is hyping or marketing a game too well and not completely delivering on promises (often imagined) due to budget constraints, design or technical challenges and often just inflated expectations. This happens with products that a perfectly fine but aren't what people expect, and products that "work" but are buggy or don't deliver all features immediately.
See all of Peter Molyneux's games post Bullfrog, No Man's Sky at launch, Cyberpunk 2077, Magic Leap. I agree that putting Playdate even in that category because the SDK won't be ready at launch is kind of ridiculous.
