It lets you "add game", but then gives you the choice of Linux / Windows with a Wine version / browser, and you have to put in the path.
So for example, in Lutris I could have "every Zelda game" or "every Castlevania game" as a filter. Castlevania needs MSX, NES, Gameboy, SNES, N64, DS, PSX, PS2, and Wii emulation; and one of (Steam, or PS3 or X360 emulation) to be reasonably complete.
I suppose I could create a Linux shell script that daisy-chains into the correct emulator, but that would be quite clunky compared to Lutris, which is still pretty clunky. And I wouldn't be able to filter to that, nor sort them by release date.
We do get a lot of German tourists coming to visit the northwest of Scotland - quite often a queue of campervans with their fancy license plates queuing up in Inverness. You can be stood on top of a mountain in the northern highlands, and not see any evidence of another human being from horizon to horizon. Which is also terrifying in a way - the traditional "Land's End to John O'Groats" cycle does include quite a long way away from civilisation if your bike decides to have a mechanical.
German tourists always most welcome here, ofc. Even more welcome if you bring some konigsberger klopse and some robust dunkelbiers with you; will swap you for whisky, we've got loads.
