Both other guides here, and almost all guides over on TrueAchievements show ways to grind the most efficiently. That's still either mind-numblingly boring, or requires some skill and focus for a stretch of time, depending on the minigame. There was one other guide on TA, buried beneath the grinding ones, that's by far the best method and I just want to highlight it here. This guide
does not require any grinding and you'll get
the trophy in less than an hour!Here is the link to the TA guide:
https://www.trueachievements.com/viewcomment.aspx?commentid=...Throughout exploring the DLC you can find stacks of Nuka-Cade tickets, worth about 900 tickets each. They're usually found in the final room/building of each area. During my playthrough where I just did the story missions I ended with 7500 tickets just from collecting these. This method involves using a glitch to duplicate your found tickets up to the 100.000 required for the trophy. This video showcases the general glitch:
You just need to build three items in any settlement; a
Conveyor Belt - Elevated Power Junction, a generator to power it and a
Conveyor Storage. You'll let your item roll over the conveyor belt into the storage unit, but you pick the item up at the same time it's deposited into the storage.
Now to duplicate the tickets you'll need to do an extra step, shown in this video:
Drop a stack of tickets (that's less than 30k tickets or the glitch doesn't work properly) on the conveyor belt and perform the duplication glitch on them. Time your pickup so you'll grab seemingly 1 ticket into your inventory, and have the entire stack show up in the storage unit. For demonstration's sake, let's say my stack was 29k tickets.
Drop your "1" ticket from your inventory on the floor.
Next, pick up the stack of 29k from the storage unit and also drop them on the floor, so both are on the floor.
Now for the magic trick: Make a Quicksave and quit to the Main Menu. Once you reload that save, your stack of "1" ticket will have changed to also contain 29k tickets, the same amount as the other stack. So now you have two stacks of 29k tickets, or 58k once you pick both up, doubling what you had!
From my 7.5k tickets, I had to duplicate 5 times in order to go over the 100k required for the trophy (ending at 120k). It took me about 20-30 minutes to understand the setup and find the right timing for the duplication, but after that I did all my duplications within 10 minutes. Meaning
this trophy only took me 45 minutes!To actually get the trophy, make sure to go to the Nuka-Cade in Nuka-World and press "Redeem tickets"on the computer inside.
