Asylum
The Witness
Ben Jordan 8 is promised to be released this Christmas, but who knows...
Nelly Cootalot 2
Botanicula and Samorost 3
Gabriel Knight 4 from Telltale Games
btw Did I mention how I'm really tired of sequels? Hopefully they'll be great, but also something completely different and unexpected will manage to top them.
I'm not forgetting about Deadlic, Boakes and King ART (Book of Unwritten Tales) - I simply haven't finished all their previous games yet, so I better don't rush into the new ones.
