Sadly, as tutorials aren't plentiful, there arent any nearly as narrowed down as the type of game you want a tutorial for.
I'm not going to complain about your overly-ambitious expectations (I went into the DarkBasic community convinced I was going to make an MMORPG) but I cannot emphasize enough the importance of starting slowly. If you start huge, it's most likely that you'll run into an error that you won't be able to solve -- this could discourage you from programming in DB altogether. Start with Pong, Monster Hunt, and Binary Moon's Limit Rush...they'll teach you the basics of game development (code organization, optimisation, debugging, etc.)
Hope this helped...
Remember, anything is possible in DB if you're good enough of a coder...and you only get to be that good of a coder by practicing gradually.
