As far as presentation is concerned, Dishonored Definitive Edition certainly does look noticeably better than it did on PS3 and Xbox 360 – higher resolution, better textures, more vibrant colour - but it’s essentially on par with the original PC game running on half-decent gaming hardware.
In content terms, this is the same release as the Game of the Year Edition that came out almost two years ago.
Is it a “Definitive Edition”? Not exactly. Dishonored Definitive Edition incorporates the superb original game, the three pieces of subsequent DLC, and some additional in-game bonuses.
