I might just be lazy, but I think having demo scenes with everything set up will help a lot. You'd be able to test the limits of the asset yourself, and it'll allow newcomers to learn quicker and ask lesser questions. And letting people play the demo scenes on your website would also help the asset grow. So far I haven't seen any demo scenes that really shows what GC is capable of, and I'm having a hard time exploring that myself.
For example, you can make a Survival Preset. This could make use of Stats and Inventory (note that I am taking into consideration those that don't have a particular module, and won't have access to that demo scene, but I think Stats and Inventory are the fundamentals of a survival game). And don't just use a bit of each. Try to make the most use of every module. Then you can make an Adventure Preset which makes use of Dialogue and Quest. Then "Run and Gun" with Shooter and Behavior. And an RTS preset, which focuses more on a different type of interaction, rather than trying to use all the modules.
A big problem I found is knowing which actions I should use to best achieve what I want. Yes, people have said to me "you have to be creative". But look, most controllers on the asset store comes with the best settings out of the box. So you know right away what you can achieve with it. Personally, I don't want to spend hours messing around with different actions, trying to get the "best settings out of the box". I want the best settings as soon as I open the box, then I can easily adjust it to my needs. Only you know the "best settings".
