But to actually respond properly:
I had seen some minor controversy brewing about the backer versions of some cards having less interesting artwork than the retail versions, and I kind of see both sides of the issue since as they say in the post, they do also need retail investment to keep the game going after the Kickstarter's run its course, and that's going to involve needing some people to double-dip to support it at retail until a second set of entirely new cards are ready to go.
The problem is that the backer versions for some of these cards are not great.
The problem isn't so much that they're using stock art since that's pretty common practice in TCGs (
even high profile games like Pokémon do this to fill out sets), but the way they're using it feels so safe and
boring. They haven't picked out fitting backgrounds that properly complement the chibi art, they've just used a generic recoloured texture that leaves no impression whatsoever, so when they're compared to the unique original art on the retail versions it's easy to understand why the backers are disappointed with their promo versions.
