Eeeeeeehhh... It's a book targeting a very niche group of readers. I wouldn't be too proud.
Now if Stephen King or someone of equal fame were writing it, I'd be proud as hell.
Yeah, but this is the thing...you get your name in something (perhaps it happened to me, maybe or maybe not, it doesn't matter). At first you think, wow. Then you realise, big deal. Because it really doesn't matter. Nothing changes.
In fairness, achieving mastery over a difficult skill - like those really good at PvP, or writing a book, or playing a top notch guitar solo...that's actually more impressive in my book. A name on a page...that feeling is like a sugar rush, fun and ego stroking, but it won't last or satisfy. No sour grapes involved!
