Thanks for sharing. This is not an RPG. The WBG Core system is a eco system in all our games. All our products use what we call the universal item drop. Basically you have a 20% chance to get an item from another game when an item drops in any game including our Hide & Find games. We built this system because its the most common components for all games in general and lump it into a single system all games use. So players can access all items for all games. They can also craft items for all games pending they have the recipe. I'm also building our in app store that uses a single payment processor. I'm a solo dev. So I need to build things that can be recycled and save me time and effort. By building a "Eco System" (described by players), I build once, reuse code and controls.
Anyway, thanks for sharing your feedback. I'll post more picks as I get more stuff finished for this part of the system.
