Leading up until Uncharted 4's launch, I spent time playing through Uncharted 1-3 (basically a binge play, lol). It doesn't cease to amaze me with the level of work that they did on those original games and what they were able to unlock in terms of the potential of the PS3. When I played Uncharted 3 a couple weeks before Uncharted 4 was released, I still was blown away by the graphics. When Uncharted 4 came out, I spent a lot of time just looking at the scenery just in absolute awe. They really did out do themselves and set a very high bar for the PS4.
BTW, Last of Us 2 is on the list to be unveiled at E3. I can't wait
