I'm sure everyone here knows about the situation with the Red Cross and how they went after the games industry for using their logo (even though the industry's been using it for well over 2 to 3 decades and that they only recently started reinforcing their trademark as of a few years ago).
The most obvious effect of this is Id changing the cross on medipacks to pills in the recent re-releases of the classic Doom games (notably BFG Edition).
But really, does that affect us, the Doom Community, at all? Does that stop us from using the cross symbol in our mods? I'm sure that there are those who wouldn't use it out of respect, but beyond that, is there anything stopping us?
