Classic Game Room presents a CGR Undertow video game review of MANIAC MANSION on the Nintendo Entertainment System (NES). Maniac Mansion, from Jaleco and LucasArts, was initially released on the Commodore 64 in 1987, not until it hit the NES in 1990 did this point-and-click adventure game become well known. This CGR Undertow video game review of MANIC MANSION features NES video gameplay footage and commentary from Classic Game Room's Derek.
