@nibar,
for my part, I'll simply say that keeping some of those entries around has served me well, since, as you have said, some of them are abandonware and no longer have support provided for them... Sometimes it's necessary to update the entries with that kind of information and to keep them around more for historical purposes or for posterity's sake, since the forum does grow over the years and people will hear about this or that game; it's nice to be able to read about it even if the game is no longer available.  For the life of me I still don't know what Grizzly Gulch is, but people mention it regularly, thus my need to go back and read its entry to collect as much info about it as I can to hold educated conversations concerning that particular game.

@Nibar, we've had this debate before.
First, I think your exaggerating with "over fifty percent" of the games having broken links, but certainly if they're a developer that is still going such as draconis, feel free to report them, since if we don't wknow we can't fix them (I fixed links in Sarah's entry just recently for example), and sometimes links can change just because a developer has updated their site, or because someone who previously hosted games has changed their mind (bladestorm360 for example hosted several games onhis site for quite some time which are now not available). This is also why it helps when people who are hosting abandonware games actually host them perminantly and provide links rather than just going "here's the game on dropbox" and just passing it to their friends.

This is also why we add links to the game's webpages, since often the developer's own site will host the files even if the direct download link on audiogames.net isn't working, I recall this happening with several of draconis games at one time, their own site was fine, but the individual setup files to their games had moved.

Secondly, in some cases like Bsc,  Code factory and bavisoft, yes we do keep the games around for historical purposes, and because on occasion games have been released as abandonware later on, that happened with DanZ's games, actually I would love to see Bsc's titles released as abandonware so everyone can enjoy them at some point and part of the reason I keep the pages up with the arning is in hopes the developer will do that in the future.

In other cases games may simply be temporarily unavailable, but might be available later due to site hosting issues on the part of the developer, for instance Superliam was not working for quite some time, but now it is.

Lastly however, I will point out it's quite legitimate for us to say "555 games in the database"
This is an informational site. we do not make or maintain the games, we are not  responsable for hosting them, and what developer's do isn't under our control, we can just write about what we find, and if something changes, well that's not exactly our fault, ---- we'll do our best to fix things of course (especially if people let us know what the problem is), but ultimately we're only human.

@Fabi youch! I thought I fixed Kitchinsinc games recently, I'll go and do those again, (something of a pain but a job that needs doing).
i'll also let Aaron know the japanese games need links fixing, since I don't have the links for those but I believe he does.

Okay, all of Jim Kitchin's games are now fixed, wooo! that was quite a job, but i'm glad it's done since I don't like the thought of people not getting to play Jim's games.

License to tdv changed along with a note on unknown status, I also did this for Solara as well.

Shame, I rather liked the game, but I'll change the license to unknown and put a note on the page.

The problem with the code factory games, and indeed the bavisoft ones is they've not officially been released as abandonware so we can't really link to anyone who hosts them in case the site got in trouble, indeed a couple of years ago I did hear a rumour the code factory games were still on sale somewhere, though whether this is still the case I don't knoww exactly.

It's actually a shame when developers vanish not! giving their stuff as abandonware, but there's not a lot that can be done about it officially.
