I love you 200. You could potentially expand this to have map packs as well, jump & competitive. The only issue is that the comp pack would have to be constantly updated, and I guess the jump as well to a lesser extent.
If Jump Academy CDN allows hotlinking from other sites, adding all the jump maps should not be a problem.
It doesn't block hotlinking, so you can download and repackage maps, but I wouldn't recommend grabbing all of them since there are a bunch of older map versions and unpopular maps.
Perhaps give players sample map lists to choose from, and redirect them to the full list
with instructions on how to install. Feel free to point the sv_downloadurl
to us though, but please give credit.
