Sure you do... BONK!

You mean Hannah Fry? No, I think this isn't her.

Basically all the Lego games (although 13y olds might already find them too child-like, depends...).
They all have split screen, so are suitable for couch (or desk) coop.
Also the slightly older ones are quite inexpensive when buying them during sales (a few €).

Special recommendation: Lego City Undercover.

Another fun couch-coop-capable game would be SuperTux, a Super-Mario-Cart like game.
This one is OSS and therefore completely free!

Oh no, this is getting increasingly complicated... from a combinatorical perspective alone I now already see the potential of mortally insulting 3/4 of the people I will be meeting... 😯

I don't remember Pokémon Red/Blue and am a parent... So this means I am considered young? 😀

You are right. Just remembering e.g. the recent farce with the voting for Bundesverfassungsgericht...

Ok, this is bonkers. Although the risk of contamination with foreign insects via transit is real (we e.g. imported the Tiger Mosquito from the US via tire shipments from the U.S. into Europe some years ago...), using that as an excuse to search passenger cars is quite a stretch...

Well, Bundestag is dominated by the CDU and she is a CDU member. So... 🤷‍♂️

And yes, the article is written more like a casual political comment and the German original also is a bit awkward, so your impression is right.

California has done searchs for ‘bugs’ before but don’t know if the still do.

I guess that is not "Bugs" as in butterfly?

Just owning them or actually using them? What are the fines?

Ok, expected this to be covered legally somehow.
Also as I assume that freedom of movement would be a value you are regarding highly in the States.

Makes sense. Would also just generate work for the police forces with probably only low level violations to be uncovered.
Being practical is a good approach.
