Video cost too much money, and "training video" never shows what you need, better written document PS in Canada, we are charge per MB downloaded (video included)
I have no idea how to create a new profile, and that would not work as it will need another email/login Beside I do not just want the collectible for the Mastery, I want them all, and I can not find 90% of them without those guides, and the guides by TSWMania are the best
All profiles are linked to the same email login, just go to the profile screen, choose switch profile and create a new one. Although as you say the advice was more aimed at people who already have them all rather than those who can't find them, unfortunately as DTG can't be bothered adding trophies/achievements to routes anymore there is zero incentive for anyone to make guides to find them..
Do what I do... wander around until I find something (I found most of the Riviera collectibles just by walking up and down the platforms at each station). Take the opportunity to explore the world and walk around until you find them
