I definitely understand! I've been in that spot plenty of times myself. I've added a few more community copies.
I had the same thought about the longevity of a Monster Guts game, which is why I developed Medara Village in the first place. If you haven't already, check out some of my other MG supplements to add more options for monsters and scenarios to your campaign! Most of them are free, too.
Let me know how your game goes! I'm always happy to try to answer any questions you might have.
