Pre ordered it today. Very excited. Absolutely adored the last game (enjoyed it vastly more than Uncharted 4 for example) and I have very high hopes for this one.
Not sure what it is precisely, but something about the formula of this series has just really appealed to me very strongly, they're just really damn fun to play and I thoroughly enjoyed 100% both the previous entries. I guess its mostly the level design and traversal but the combat as well, just love it so much more than Uncharted. Everything I wanted Uncharted to be and do is basically in these games which i guess is ironic since the first clearly took notes from U1 and the second notes from 2 and 3. U3 I was similarly let down by so I feel like this series specifically exists to address my frustrations with Naughtydogs games haha.
