Toon sprang to mind right away for me, as being light years easier,. [As I recall, only 2 d6 are used, period.] The fact that your character never dies, but must wait 3 real life minutes might help the situation a lot.
Not so sure if the book is still being printed. I ended up buying two copies of the base book, in paperback, and BOTH books started to lose pages from the binding, UGH.
Our D&D group had a 9th grader in it last campaign, and it was my 2nd campaign [as a player] ever. I know the exact situation you are talking about. I started out the gate as a 6th level or so Druid, and the paper work I had overwhelmed me. I spent 90% of my time trying to choose what to do, often going for the more impressive, not so much the grind it out practical. Then again, I have ADHD and I’m known to think outside the box on things [[Look at the HAGGLE games played in this thread, if you don’t believe me.]] and If I had to bet, I would put money down that the 9th grader has ADHD as well. I played as a Fighter in my 2nd campaign, and not having to memorize [read having to spend times guessing what spells I’m going to need] spells sped things up a lot for me. Perhaps there might be character types you might want to steer them towards for next campaign.
I’m 27, building my first character was a LOT like a “kid in a candy shop”, the DM and another player had all of the 3.5 books between them. I picked up things that looked cool and flashy, but were very limited in use. Likewise, just because an item can be used in game, doesn’t make it practical. You might want to steer them towards certain items here, as well.
Our group has talked at length about 4.0 and how dumbed down it is. There is an option where you can get your second wind [so I’ve been told] and take one round to rest, taking no action. You get a majority of your HP back next round.
We all agreed that the game is getting stupider, [[and Magic The Gathering seems to be going the same way.]] and we half jokingly decided on a D&D 3.75 where we take the best rules from the past 3 iterations, ignoring 4. We also employ some house rules:
1.3 Natural 20s in a row, in combat is an instant death to the creature you are fighting. [We actually had this happen, ONCE.]
2.Once you are at 0 hp, you don’t die at -10, but you die at -X where X is your base CON
I’m pretty sure both of these are un-original ideas, but we decided to keep both of them
