It's fine, but it doesn't get me excited nearly as much as the old Nate's Theme.
I'll just re-post what I said in the OT. Listening to the OST on it's own a few more times has only reconfirmed what I felt when I typed this up:
Y'know something, I don't think the soundtrack is bad, in fact there are quite a few good tracks on it (
this makes me want to rope swing in real life), but the main menu is like anti-hype. Turning on UC2 for singleplayer sessions and hearing Nate's Theme is still so good. Or loading up a multiplayer match back then while
Reunion cued in the background relaxing the hell out of me before I shot everyone in the face. Or
The City's Secret. Or
Marco Polo. The UC4 menu doesn't get me going like these did. Jackson's solid with ambience and action music, but it's really missing that exotic, adventurous longing that Edmonson had in his work.
EDIT: Or something like this forgotten gem
god tier synth + woodwind/flute/whatever cue I heard during my Uncharted 1 Remaster playthrough
