I completed the game yesterday and I the game managed to keep me engaged throughout whole game (my first impressions on the game is in old post). Canis Canem Edit uses fundamentally the same game mechanics and system as GTAs. I do not find GTAs very entertaining while Canis managed to do the magic. While in Canis Canem Edit there are some frustrating moments when change in camera and controls directions makes thing really tricky mission are more varied and balanced (for my skills) than in GTAs. Moreover, I find the theme of Canis Canem Edit more attractive than GTAs’. Specially, sarcasm and irony in Canis Canem Edit mostly works; character stereotypes, at the best, are a part of a joke.
A small disappointment to me was to notice that most of actions do not not influence how NPCs react to Jimmy; only the missions change respect values and behaviors (this said, flirting and giving gifts will have an effect to some NPCs, but not all, I think).
