On Monday, Tracey John discovered TT Games has an in-house rule about what games get the small block treatment: the properties have to be age-rated for young players.
One might argue the "Indiana Jones" series and the "Batman" franchise have their fair share of content targeted at someone other than kids (i.e. the pencil trick from this summer's "The Dark Knight"). But MTV Multiplayer understands what the TT Games people mean.
With that in mind, MTV Multiplayer can deduce what franchises might not ever get the "LEGO" treatment.
