The first:
A horror puzzle game with a bearded guy and a weird (orange and puppy looking i believe?) companion creature. I believe it was kind of free roam.
The second:
A game in which the game starts off on a sort of airplane craft, and you see 'nemesis' in the sky, a large snail as far as i remember. The game is a free roam, horrorlike puzzle game as well. Usually in the cutscenes you see the silhoutte of a thief, and later in the game they added combat where the free roam got pretty crowded by zombies and pirates.
