I think I'm one of the only people who didn't notice any of the product placement in XV on first playthrough, Lol. I think there are at least 3 main examples? Cup Noodles, Vivienne Westwood, and then some camping equipment company?

The only one of those I noticed in my first playthrough was cup noodles, but that brand doesn't exist in the UK (or is not mainstream enough to be in the average supermarket) so I had no idea that was a real-world brand. I just assumed it was in-game brand they'd made up. Then Vivienne Westwood I skipped because I didn't bother with the wedding dress mission on my first playthrough. Then the camping company I hadn't heard of either!

Ignorance is bliss I guess.
