Found a great article that describes the differences in the gun manufacturers in Borderlands 2. There are a lot of videos on Youtube of gameplay, and I’ve seen about 30 different guns already. I like how the “cheap” Tediore look, and the Orange/Aqua stripe combo of the Maliwan weapons. And that’s just the color schemes, the physical ammo and loading animations are pretty damn crazy as well!
Brink might be a flawed game that few people will play, but I”m at least going to be checking it out for the art direction:
Kotaku has a decent article about it, with a link to the Brink Developer’s Diary. I personally like to use IGN’s websites for doing artwork research, they seem to archive every piece of concept art and official screenshot in a high resolution. Here’s Brink’s gallery on IGN.
