I don't know about other genres, but
Old Man Murray had an interesting (tongue in cheek) theory on what happened to "Adventure Games".

And, yes
Gamemaker (along with
Flash and
Photoshop) is one of the three best programs you can possibly put on your computer. It turns
anyone into a potential indie game developer.
I've even got a few games of my own in the works, including a sidescrolling action/RPG I call
Kou's Quest, a 2D shooter called
Uchuu Keisatsu Gardro-Z, a fighting game called
Senki Fist, and a brawler I call
Grandpa Kicks Butt (where you play an old man with a cane on a mission to rescue his grandson. You beat crooks to a pulp with your cane shouting "Get off the goddamn lawn!" and "Where's my grandson ya little bastards?!").
Expect an update on your book in couple days. I haven't had much time to read it lately, between drawing model-sheets, and my day job riding me extra hard lately.
To Rock's Sunglasses: Nothing wrong with hanging on to old games.
