I loved Amnesia, It's exactly what I'm looking for right now! (although I'm not exactly in a horror mood)Valiance said:Define what you mean by compelling?
Braid, Trine, Amnesia: TDD, I think all of these have compelling single-player experiences, but they might not be for you, and admittedly, end up being linear.
Are you looking for an open-ended sort of sandbox or open RPG, or more of a set-on-one-path-mostly linear single player "epic" story experience?
Trine sounds interesting.
And I've enjoyed both sandbox games like Red Dead and linear games like Amnesia, whatever you have to offer.
And thanks everyone for the suggests so far! I'm looking through reviews and demos and such of the games that have been suggested and I haven't yet played.
