Just as an update, we tried Zubo this morning but with her ADD brain, she had a little trouble with the timing of the battles. It was also a bit annoying that you would use the touch screen for almost everything except when there was talking and then you had to hit A. She got a little irritated with that. You were also right about how she is a bit "spoiled" with graphics because once I showed her Pokemon Y, she put Zubo down in a big hurry.
I think I'm going to go ahead and get Omega Sapphire. She is having fun skating around in Pokemon Y but I do think that Ruby might be a little bit simpler as far as interface. She continually surprises me though so who knows.
I'm sure this has come up a million times but how annoying is it that Nintendo still only allows one save file for a lot of their games? I am playing Pokemon Y so I didn't want to overwrite my file so she has to just play on my character. She doesn't know how to save so it won't affect my file but it's still incredibly annoying. I guess their cash cow is working because I'm going to buy Omega Sapphire so she can play too so go Nintendo (wink). Thanks for the suggestions.
