Dawnsinger: Anyway, I'm currently checking out the site and found that you have the red X in the results, but it doesn't remove the result but forwards to the gog page. At the same time, hovering the mouse over the result shows the red line regardless of the position the mouse hovers over. Is this my TOR browser only or a general bug?
There are two places red Xs should show: immediately to the right of each search filter in the left bar (allowing you to exclude that filter, rather than require it), and immediately to the right of each selected filter at the top of the results (allowing you to remove the filter again). It sounds like for you, one of those red "X"s shows over/inside the information for a game? That's definitely a rendering bug. It's quite likely that this is caused by the Tor browser. Can you tell me its version, or ideally the version of Firefox it's based upon? A screenshot might also be helpful. I'll attach one of the way it
should look. (FWIW, that's in dark mode; depending on your OS/browser settings, you might also get the website in light mode.)
Dawnsinger: I'm trying to find games that are online co-op (direct connect preferred, but mediated through some lobby may also be acceptable); MMOs aren't a thing on GOG so that's less noise, but checking the co-op tag also brings up local co-op titles which isn't what I need. So in fact I'm looking for "full game co-op" (not just some co-op maps in an otherwise PvP game) AND that co-op works via direct IP or lobby, for 2-4 players, with a self-hosted ad-hoc / non-dedicated server (like NWN, DoS or Solasta).
Though it seems like the official tag data doesn't have this kind of detail, and the community based tags tend to be exaggregated at times, so you're probably not the one to ask about such, but then again, you poulled a whole lot of data into usable form that also isn't inside the official tags, so... ;)
You could try the free text search in combination with filtering on the co-op feature. I don't know this space, so can't judge how useful the results are, but
lobby,
lan and
direct ip all give a couple of results, while
requiring the co-op feature but excluding the "local co-op" tag gives many more. (That unfortunately also exclude games which offer both local and non-local co-op, but at least it's a start.)
Dawnsinger: I also don't feel the sorting of the tag list is ideal, I'd prefer an alphabetical list if I'm to add the community tag "online co-op" (which I didn't find in the list, unless "multiplayer" equals online-multiplayer instead of any form of MP, given there's also "local multiplayer"). Plus, the tag list is too long to conveniently scroll in the provided frame, so maybe that one could be made twice as long?
I agree that this is not ideal. I feel alphabetical sorting would be worse, but I hope (on the medium-term roadmap to investigate) to eventually split the tag list into a bunch of smaller subcategories for perspective, genre, theme, setting and so-on. I worry about the completeness of the data, since if I do that, I'd want each game to have at least one tag in each category, which might mean a whole lot of manual data-entry.
