Okay, so Binary Domain and Syndicate.
First off, I didn´t really like the BD-Demo all that much but the full game is WAY better. Both Demolevels are from the first third of the game when your Rifle isn´t all that good. Later on, Dan´s primary weapon becomes an enjoyable piece of destruction equipment
But it´s the story and the mood that make this game better than average. The whole "when does artificial life become "life", what if you´re a robot but you don´t know"-thing has always interested me and that´s basically all the game´s about. I´m not through it yet, should be soon though.
So far, around 10 hours of excellent entertainment.
Syndicate on the other hand, I only got because of the coop-mode but turns out, the Campaign has an extremely well-set mood to it, the dystopian and hostile feel to it is pretty great
Can´t say much about the coop yet, since I´ve only played the western europe-map from the demo with other people. I like it so far
