American McGee's Alice
Okay, usually 'HEY! LET'S TAKE X PROPERTY AND MAKE IT ALL DARK AND GOTHY!' makes me want to walk away in the other direction, but, this one gets it right. After a trauma that leaves her orphaned and in an asylum, Alice has retreated back into Wonderland in her own mind, battling her inner demons to try and get a grip on her own sanity.
