through Wonderland, which was rejected by EA. Another approach involved the projection of Alice's parents and acquaintances onto the characters of Wonderland and Alice investigating the cause of her father's death. After discarding this concept as too complicated, McGee ultimately aimed for "the simplest story that told the most". Aside from the reappearance of characters and locations mentioned in the novels, no references to the novels' plots are made in the game, as McGee did not intend for the game to be a continuation or competing version of Carroll's work. The development team solely used the original novels as reference material, ignoring film adaptations and other derivative works. The game's title, which includes McGee's name, was chosen at EA's insistence, primarily for the ease of registering and protecting a new trademark. McGee admitted that he did not support the title, as he opined that it put the rest of the development team in the background. American McGee's Alice is McGee's debut work as a lead game designer. Development and marketing EA licensed Ritual Entertainment's Heavy Metal: F.A.K.K.² engine, which is in turn a modified Quake III Arena engine. The most notable changes in the engine include the use of the Tiki model system, which enables the engine to use skeletal animation among other things, the Babble dialog system which enables lip synching of audio with character animations, dynamic music system, scriptable camera, particle system and extended shader support. The changes implemented to the engine for Alice remained minimal however. The game's .bsp files even retain F.A.K.K.²s headers, albeit sporting a different version number. An early version of the game featured the ability to summon the Cheshire Cat to aid the player in battle. Though this feature was removed from the final product, beta screenshots of this version do exist online. In the final product, the player can press a button to summon the Cheshire Cat at any time, though he merely provides cryptic advice on the current situation and does nothing to aid Alice if she is being attacked. An Alice port for the then-unreleased PlayStation 2 was also in development but was later cancelled, which caused Rogue Entertainment to shut down, another decision which angered American McGee and resulted him leaving EA in frustration. The game's box art was altered after release to show Alice holding the Ice Wand instead of the Vorpal Blade and to reduce the skeletal
