I can vouch for Batman: GCC because I played Conan and love it. Don’t worry, you won’t be disappointed.
You learn what has true potential and which projects reek of inevitable disappointment after a period of constant backing. Pacific Rim, for instance, had enough red flags to warn you that you should steer away from it. Whilst other projects, even before they go live, you find people are anticipating and they back them in droves. Zombicide: Invader comes to mind, of course, but even new ones like Arena: The Contest. In the case of the latter, it’s obvious that the project owner was able to garner hobbyists’ interest way before the KS began. He managed to earn their respect and interest and showed initiative. Now I’m not saying it’s a sure hit, but at the very least he did much more than the bare minimum to earn that initial trust.
So just learn to do a decent amount of research about the project and the designer’s background before jumping in to back it. (Then just relax and enjoy what’s coming! 😜)
