Hardest? Take your pick, any of the MYST games, none of which I ever finished, those, IMHO, aren;t even real AG's, but a collection of really hard puzzles strung together with the thinnest of stories. But amongst those kind of games, I have to agree with some here, Schizm is just mind blowing hard, like others said, even with the walktrhogh I didn't understand, and sometimes couldn't fnish, the puzzles
Easiest? There are quite a few, but Dreamfall comes to mind first, again, almost not an AG but an interactive story; Still enjoyed it, but alas
