Cyberpunk 2077

Note that, despite the achievement description explicitly saying to find all dataterms, you do NOT need to find all of them for this achievement. You only need to find most of them. There are over 130 dataterms in the game, but you only need somewhere around 120 for this achievement. While that may not seem like a big difference, it is - you don't need to agonize over locating random missing ones.

Fast travel dataterms work a bit different than other open world games. In Cyberpunk, these fast travel points are not marked on your map until you travel near enough to them to activate them. Once you're close enough, they automatically turn on and become usable without you needing to do anything. This is in stark contrast to other open world games where all fast travel points are marked on your map even before you've enabled them, allowing you to travel to inactive ones to activate them. Additionally, there are a massive amount of fast travel points in the city, which is handy to be able to travel near to where you want to go, but can make tracking all of them down a nuisance, since there's no way to tell where you're missing any. However, by the time you complete all gigs and NCPD hustles in all areas, which is required for all achievements, you should have come across enough dataterms to unlock this achievement. Running/driving from hustle to gig to hustle as you complete everything on the map for achievements will activate plenty for this achievement. I unlocked the achievement well before finishing all gigs and hustles.
