Hotel Mario is a puzzle game developed by Fantasy Factory and published by Philips Interactive Media and Nintendo for the CD-i in 1994. The primary character of the game is Mario, who must find Princess Toadstool by going through seven Koopa hotels in the Mushroom Kingdom. Every hotel is divided into many levels, and what the player must do is close all doors on each level. Killing a Koopaling on the hotel's final level takes the player to the next building. After Nintendo decided not to have Philips create an add-on for the Super NES, they gave Philips permission to use five of their characters in games for Philips' CD-i. There wasn't a lot of time for the games to be developed and there was little funding. The games resulting from the license were widely criticized, with "Hotel Mario" being known as one of the worst "Mario"-centered games, due to the animation of the shutting doors, the non-working controls and especially known for the cutscenes that used full motion video. The CD-i was considered a commercial failure and the games became valuable because of their rarity.
