well, It seens to be a good idea... What the books you recommend? I'm reading PHB, DMG and Monstrous Manual.
Thanks again
I’m probably biased, but my first choice would be
the c. 1981 Basic Set. It is, unfortunately, the one basic set they don’t sell a PDF of.
Rules-wise the c. 1983 Basic Set (which someone linked to above) is almost—if not entirely—identical. While the 1981 book is organized in the manner of most RPG books, the 1983 set tries to be even more beginner-friendly. It has a “programmed adventure” (a solitaire adventure in the choose-your-own-adventure style) to help explain the game.
There’s an earlier Basic Set too. Many (including me) find it more “flavorful” than the later sets, and plenty of people learned the game through it, but I think the later sets are easier to learn from.
Now, the Basic Set rules are different from the AD&D rules. They are highly compatible however. What you learn from the Basic Set will be applicable to AD&D. Stepping up to AD&D just means adding some additional rules and some tweaks to the numbers.
It’s not the only way to go, but—as I said—it’s the way a lot of us entered the game.
oh.. you really know about Ahura Mazda and Zartosht!!!! that's unbelievable!!

Personally, I’d expect any serious follower of one of the Abrahamic religions to know about Zarathustra. But I have unusual expectations.
