How I think American McGee’s Alice will end:

As it always has been, Wonderland is nothing but Alice’s dream and she will wake up from the nightmare after defeating the Red Queen. She wakes up to the cruel reality that she is still in the asylum but is at ease to know that Wonderland is at peace again. 

Meh, simple ending but I’ll find out what it really is soon. (yeah nvm, that ending would be too simple for American McGee’s Alice…)
