A fantastic reboot to the franchise, and a great adventure. A pretty good set of achievements too; some Story, some side-quest and a bunch of Collectible/collectible-like achievements.
Nothing really missable because you can fast-travel anywhere to mop up anything you missed the first time through.
Note; For the many collectible-like achievements, they are all made easier by buying books from the hub areas in the game; this shows the locations you need to hit on your map and makes finding the things much easier! So as you reach each of the three main hub areas be sure to buy all the books you come across - the first will be in the Vatican, see When in Rome, and tick off Ecco! whilst you're there.
A very accessible and fun 100% for sure!

Collect 50 Journal notes.
Collect 50 Journal notes.
You'll get this on the way to Archivist - just be sure to pick up all the journal notes you see lying around the place as you play through. This first 50 will be pretty easy and likely come up in natural play.
As with all the collectible-like achievements, buy the book! The guide books from each of the hub areas will highlight where the notes are on your map.

Clobber an enemy with a guitar.
Clobber an enemy with a guitar.
As with the other similar achievements (e.g. Pest Control or Celestial Delight) there are loads of guitars lying around the place that you'll easily spot as you play.
Grab one, and then the easiest thing for the achievement is to sneak up behind an enemy and then hit them.
Capture 50 Photographs for your Journal.
Capture 50 Photographs for your Journal.
As you play through the game, periodically a camera icon will appear in the top-left of the screen - when this happens whip your camera out (Up on the d-pad on a controller) and take a picture. After 50 it'll pop.
This isn't hard, but is worth taking all opportunities for as you play through - to minimise mop-up after completing the story.

There are three underground boxing clubs - one in each of the main hub areas. At each one you must defeat three opponents, the third is the local champion. Beat the champion in each to unlock this achievement!

Bring all radio frequencies to Gina.
This is in a side quest in Gizeh which you can start by talking to Gina in Nawal's tent. There are four frequencies to collect.
This is an Objective, rather than All-the-things, as the quest gives you a map with four areas, so its basically an Objective to complete the quest rather than collectible-like.

This is easy if you buy the artifact guide books in the shops in the hub areas (Vatican City, Gizeh and Sukhothai) - once bought, all the artifacts will be highlighted on your map so they are super easy to find.

Collect all Journal notes in the game.
This would be hard - except for the guide books you can (and should!) buy in the three hub areas. Buy those and the locations will show up on your map. Make sure to pick them up as you play through naturally, and just fast-travel back later for any you've missed. You should pick up Field Survey for the first 50, and then this one when you've got all 100.
