Borderlands 2 (PC/PS3/360 - September 18th)
Pop in your copy of Borderlands (if you forgot yours, ask the person next to you to lend you a copy). Now compare what you see with these screens here. Gearbox has seriously upped on the visual department. Not just the modeling or textures but the vibrancy of color makes for a refreshing change of scenery. Definitely a far cry from the monochromatic desert-pocalypse of the original.
What about the gameplay you ask? That’s something that barely needed refining to begin with. If Gearbox has somehow improved on the gameplay in any way – and this is highly unlikely; abhorrently unlikely – then my mind will fracture.
