My daughter could handle it ~ 8-9. There's a bunch of reading and keeping track of stuff, but if you each play two heroes the game isn't overly frustrating and giving them a choice of heroes helps. The tokens from the 2nd edition help, but aren't essential if you have some paper around. They just make it a little easier. She enjoyed it and likes being able to play the girl heroes. Some of those battles can go long (read through the session reports). That could diminish the interest level considerably if you just can't get momentum and the game starts to drag.Of course, the big thing is to play games he enjoys. A big part will be that he gets to play with you, but if there's something that he likes whether or not you're there that's a definite bonus.
I don't know if something like Mice & Mystics might work. It's got a story-telling theme and the bits are attractive. Eric @ The Dice Tower has been playing it with his son and they've been enjoying it. (Of course, Eric also has the voice for it.) Just something else to consider in addition to SotM. I think it could work well for you based on what you posted.
