I'd be all over this if I hadn't already played the games half a dozen times each.
I may still be all over it.
I hope they've been bold enough to make a few changes, at the very least to the first game. Its gameplay mechanics have aged poorly compared to the sequels. I'd also like to see combat in the third game tweaked slightly, because they made some changes to the encounter design that made combat less fun than the second game. For me, much of the problem came from them sending enemies at you from every direction, often before you could react to their presence, making cover a liability, not an advantage.
Yep, poor encounter design in U3, I'm not sure who did that and why. The best example was an encounter set piece they showed in various stage demos clearly allowed Drake to stealth through most of it. But, in the full game on release, there's a magic trigger that prevents you from stealthing that segment at all, and as soon as you cross that invisible threshold it devolves into one of the most annoying firefights in the series.
For Uncharted 1, I think they should add a Very Easy mode that was in U2 and U3. I'm not sure they have the resources to make significant changes, but a Very Easy difficulty setting would only require blanket tweaks to health and damage. This allows people to play through it for the full story effect. Also, having solid 30/60 FPS will be a huge help to the game, as it was one of the reasons many found it hard to play.
