#9 American McGee’s Alice
Tumbling down the rabbit hole. Madness features quite prominently, both in Lewis Carrol’s books, and of course also in the quite deranged games based on them. American McGee’s version of Alice is like a much more malicious take on all the characters from the novels. Alice herself starts locked up in a lunatic asylum, and finds herself in a Wonderland that has been tainted and twisted and deranged by her own mental affliction. Of which she has to cure herself to save Wonderland.
