The games isn't to hard to learn its knowing when to transform the Lions into Voltron or the same with Lo-tors bing robeasts Lo-tron.
Movement is counting squares, shooting looks ok to handle but its the action dice you use that you need to keep track of that may be hard for the kids to follow still getting my head around the game I am thinking Monsterpocalpyse maybe an easier game for them to play. You will need to get the mat laminated as it doesn't sit well [been folded up to long] plus the kids may rip it..
over all its interesting we are trying to have a game when i get back from my Blood Bowl tournament.
Cheers
