I’m not really sure what to do with them. I’ve played the previous games and there are plenty of times where a seemingly random pda was super useful for a hidden, unmarked quest (and, shit, even the real ending for the first game), so I’ve just been keeping every PDA, note, research packet, USB drive, etc in my roaming stash box.
Which ones should I hang onto and which are just there for a gag/reference and some cash? I have so fucking many of these things lol
The ones that matter get locked. The rest will download into your PDA and can safely sell. The journal entries and caches will still be on your PDA when you sell the rest.
100% though? I have already found 2 times where I could offer a PDA that wasn’t locked to my inventory as a quest item to an NPC for extra dialogue and a reward. Once with Leech (the guy hanging upside down at Elevator in the Cordon) and once with a trader in Zalissya with a PDA of Sidor and some other dude conspiring to ruin his business.
Now, to be fair, I’m not sure you need to physically have the PDA on you to get the options; but I did at the time. It didn’t take them away once offered, though.
