Chronicle of Innsmouth: Mountains of Madness

They achieve this in different ways: the stunning graphics is full of exotic and evocative locations; the amazing and evocative music is never repetitive and never intrusive, but manages to talk to your subconscious and increase the experience; the presence of a party of companions, who follow you through all your adventure; the many differeent flashbacks, which increase the variety of the settings; many small details such as the flickering lights or the animated clouds; the many comic-style cutscenes which highlight the key moments in the story; the english voiceover which is very expressive and competent.

Gameplay-wise, the puzzles are good, varied, make sense in the context, are of medium/hard difficulty, are fair, and have just the right amount of clues.

On the tech side, MoM has good quality graphics (gotta love that pixel-art, motion comics interludes and hand drawn backgrounds), good animations, great original music (some themes will give you a chill or two, and the end credits theme is awesome) and a well-polished interface.
