blender 2.3 guide
If you want to know how to use blender, these are the books. They might not be up to date on the latest version, (especially the gamekit) but I managed to use both and found blender3d much easier to use. The online tutorials helped too, however there's so much missing that you need this book (both if you want to use blender for games). Maybe someday there'll be a pdf or something.. I find the books themselves a bit awkward if I am reading and following along.
All in all, if you're serious about 3d/blender/games here are your manuals.
