Game Maker 7 most likely is the simpler choice.
Its event based and has a visual programming language, so even with short concentration phases he is able to accomplish things.
3D Game Maker is one of the standard rubish TGC "create game button" products. He would need to have a serious amount of concentration to not go wacky.
EDITED: Removed the 200 in front of the 7 :$
