Hehe, I like this fic! I used to do mysteries like this all the time... ahh the memories... I was never any good at them though. And if they involve game mechanics, I don't know a lot about that either (although Google is my friend). Anyway, I really like how you described Sterling; a truly eccentric character. The way you have Sterling and John reminds me a lot of Sherlock Holmes and Watson, right down to the condescension. Isn't it Teddiursa though? The hats you'll have to come up with every chapter are going to amuse me.

That's all from me for now. Cool stuff.
