doesnt it crash your client when you join a v20 server with v21?
Old versions don't even appear on the master server without a hack to send fake version info. And even once that's done, it's not much any more harmful than the Bluzone, []----[]'s Join to be Auto-Banned, or any password-ed build server. That's right. Even without v20 players, we still have plenty of unjoinable entries in the master server.
The second of Badspot's arguments is that it fragments the community. What the hell? This isn't the v0002 to Retail Release all over again. It's an update that sacrificed gameplay features for a graphical update. It's not their fault for missing the old gameplay features. None of them are dedicated v20 players. Literally all of them still regularly play v21. They mess around in v20 for the nostalgia factor of seeing their old maps again. They are still in frequent contact with the rest of the community and typically play the newer versions.
The third of arguments is that you shouldn't download executables from random people. Badspot is totally correct on this one. But it's not Badspot's job to police this sort of thing when it's the user's fault for downloading random junk they found on the internet. It's a
computer for christ's sake. They own the property and if they decide to totally screw it over, none of us have any say.
