Out of curiosity, I tried to roll a nomad/street kid (So far I had played only as Corpo) and I noticed that on top of the broadcasting tower in the Nomad beginning there is a stash of component. Unlike the two other beginnings, the area to explore is also quite wide. Wondering if there are some easter eggs/story shards or simply some useful loot to be found there.
Apparently corpo intro is where you find the witcher easter egg. Sadly Ciri character doesn't seem to appear in the game, but once you go to your desk and open your drawer, you can see a 'retro gaming' magazine with Ciri on the cover.
It's not useful loot but its rather cute.
