I was tweaking some stuff of my DM server and I was trying to change the round time since it was only 5 minutes. I checked server.cfg, deathmatch.cfg, even the deathmatch.py to see if there was a mp_roundtime cvar but found nothing. I used notepad++ to do a search of the cfg folder for roundtime to figure out you actually do some of your config in the valve.rc file.
Having run many source servers over the years, I found this to be a bit odd since I've never seen any config options in the valve.rc file. I was just wondering why you put some options in here rather than having them in the server.cfg? Having everything in one spot is a lot easier to manage.
Also, just curious but why did you need to create a ge_rountime cvar instead of using mp_roundtime? Is mp_roundtime not a native command for orangebox or something?
