The magazine I subscribed to just did an exclusive interview with ND staff in this month's new issue, here are some of the things co - lead designer Neil Druckmann had to say about Uncharted 2 :
"We have tons of maps, over 10 different kinds of gameplay modes just for the competitive end. We have these online cooperative maps, so yeah, it's been a lot of work, but we hired brand new designers, background artists and programmers just to handle our multiplayer aspect, to make sure the single player never suffered"
"We looked at Killzone 2 alot, and actually talked with those guys about some of their rendering techniques so that really helped us push some of the graphical stuff we're doing in Uncharted 2. Then we looked at Resistance 2 and their co op mode and how they did some of the stuff. Those were the big games we played."
"I don't think we've announced this but if you played Uncharted and you got some medals, we're gonna give you some cash towards unlockables in Uncharted 2, so don't delete your save game."
And regarding no mandatory installation for Uncharted 2:
"Well, I mean, we have some of the best programmers in the industry, so obviously not everyone can create the kind of engine we do. Also, in - house here, i don't know if you've heard but we have The Ice Team, which is a bunch of programmers from ND that acutally make tools for other developers to help them come to grasp with the PS3"
