well i started with 3dgs when i was 13 or 14 but i wasnt like him. i was learning and learning by myself. i had times when i wanted to give up but then i read that when learning about programming you MUST be persistent. so i think he could learn it, if he's persistent and willing to learn that - honestly i think he isnt but hey, maybe he can...maybe

the point is, he might be too young but as long as he has a great will do learn about programming and 3dgs he could do it...

@victor_crispin - but you wont do anything with asking questions and questions on this forum...go and take yourself a lite-c workshop and start learning
