I also remember being burned on the previous similar bundle a few years ago, where most of the assets had license files stating that they were either only licensed for RPG Maker, or a vague term that they could only be used in engines that "respected Degica's rights", whatever that means. I don't think any of the resources I actually
want to use are possible to use, so it feels like a pretty big waste of money (except the "proceeds go to charity" part which helped soothe my saltiness... but I'm not sure if that's still a thing now when that big evil company bought Humble
)
It's not
that hard to find good-enough assets just checking sites like Freesound and OpenGameArt, and it's a lot less likely you'll be using those flipped assets that five million people just bought. Just lurk them regularly, check for stuff that seem relevant, slowly amass your own library of stuff that might be perfect one day, and
keep notes of licensing terms alongside the resources. Especially for audio, there's plenty of reliable options... it's harder to get stock graphics that all fit together. But IMO getting a random bundle once per year is just gonna get you even
less coherent things...
