It is completely reliant on a individual people to maintain a share with no commitment plus you still need a hoisting site to maintain the tracker.
2nd If that file gets update that old torrent is no longer valid and a new one has to be started.
1.you do not need a tracker, you only need a magnet link in the theme with the game on this site. You can create a link yourself using any torrent client to any file from your computer. Without a tracker, independently, regardless. In fact, through the client, you share access to a specific file or directory, directly, without the participation of intermediaries. This is why the protocol is called peer-to-peer. And the trackers themselves do the same thing as this site - they are just a library of links and forum.
2. yes, distributions depend on the goodwill of the seeders. But if the game has at least 100 fans, five of them will be able to stay on the distribution, plus the author if the content is uploaded by the author.
3. If the files have been updated, they need to be uploaded to the file hosting service again, if the files have been updated from the author, he simply re-creates the link, you download it. At the same time, you do not have to download the entire distribution, you rehashed it and download only the part that has undergone changes. It's actually akin to a build server. The developer can release incremental patches and add them to the game, and the player can only download new data files, without re-uploading to hosting and re-downloading the entire volume of the game.
In fact, torrents are not very convenient for small files, they are easier to download from exchangers. Taking into account of course what content you post there, because exchangers can delete both your content and your account, without warning. This is bypassed by setting passwords on the archive so that the site cannot see its contents. But it still does not give a 100% guarantee of the safety of the content. But for many small files, you can create a single distribution, the user, when downloading, sees the entire list of files in it and can select the necessary ones.
For large distributions, file hosting services are generally not suitable, since they have quotas for the amount of daily traffic and its speed.
Torrent can also be subjected to malicious code being added easier.
Any content is created by the author, its safety depends only on the author, but not on the method of storage or distribution. And trackers (personally, in my 15-year experience) are an order of magnitude safer than exchangers, because they have premoderation and feedback, while absolutely anything can be placed on the exchanger. And the method of distribution of this site, as I said, is already very much like a torrent tracker.
Some of its authors still here provide a torrent link to their distributions, I personally am immensely grateful to them for this. But most, alas, no.
