Doom and Quake mods existed in a world before sketchy download sites.  And today, most Doom and Quake mods seem to be hosted on websites dedicated to either just those games or mods in general (and I say this having spent some of this past weekend revisiting Quake and Doom mods).<p>Minecraft modding seems to be centered around a third-party controlled forum with ad-interstitial links to pay-per-impression downloads from some sketchy file hosts.  The whole thing is super sketchy.  And the fact that you&#x27;re basically patching in compiled code (that can do bad things to your system, as there is no limited API or scope-limited runtime like in Quake and Doom modding) makes it really, really scary to get those mods running.
