American McGee had this to say in a facebook post:
Questions for you:
1) If we could get the rights from EA, would you play "Alice 3?"
2) If you'd play "Alice 3," would you back it on Kickstarter?
3) If you said "yes" to those two things, make some noise - I'm trying to gauge interest in case I happen to discuss this with EA during GDC in 2 weeks. The more interest there is, the more seriously they'll take the conversation."
I don't know about you, but my friends and I liked Alice: Madness Returns very much and I personally would love to see a third game in the series at some point. So yeah, visit McGee's facebook page and leave a comment. Who knows, it may happen yet.
