Definitely Loom.
Also I'd love to have endless sequels to Monkey Island.
I really hope TLJ3/Dreamfall 2 is made. I think it will be eventually, but it's just not soon enough.
BTW, this is my first post here. Hello! I've been playing adventure games since I was very young. It all started off by me watching my dad play them and helping him out at times. I think his first game was Robin Hood: Conquests of the Longbow. Soon I ventured into the genre myself and the rest was history. I've already played many games so far, and always look forward to new games coming out.
