You're better off picking up the Telltale Walking Dead games if you haven't played those yet. Easily my favorite game from last year.
Just gonna leave this here for Survival Instinct--it is most definitely not a case of reviewer loyalty to the Telltale games.
Oddly enough, all the reviews of read of this game (which are universally negative) make it sound like a shitty 3D version of Organ Trail, a game I just purchased on Steam. If you're old enough to have played the source material, this game is awesome.
