S.H.
I didn't realize they are not comparable. Just a knock off. Have you tried to put them together. I going to my son's room now and will report back.
They work together. I can read 'lego' on the bump and 'mega bloks' on the brick. They connect as if they are the same brand. This is an example of the mega books, since it seems many think they are for toddlers and they also have a 'call of duty' and 'Halo' ine that I do not use. http://www.toywiz.com/trueheroefire.html?utm_medium=pla&a...
edit: Mega Bloks hurt my fingers. Lego sets do not hurt as much and seem to be easier to put together for kids.
