Dunno if there's much out there in actual print ??
Its easier to go with digital. If you want a book and you can afford to print a pdf, then there's a solution... Anyway, only resources I know of are:
"Hands on Dark Basic" (heard it mentioned. Dunno lots about it).
"TDK's Tutotials" (very good tuts for begginers but also intermediates as they explain things but without rabbiting on)
The help file (it's amazing what you can learn from this by gradually reading through it - whether you are studying "Hello World" or complex 3D commands).
TGC Forums. These are packed with stuff. Use the google search not the forum search as the forum search never works.
As for game-making concepts, thats something I honestly don't believe can be "taught". Sure you can parrot learn something but experience is a far greater ally. So for that I say train everyday (raw eggs optional but caffien essential).
Word of advice: polish up on your maths. i've run crying to wiki so many times for forgetting simple theorems.
Way more info than needed but my -v switch is always enabled. Anyway, hope you find something useful there. Good luck.
