Perp, well I don't think any of the other Gamemodes are as fun as PERP. Personally, I don't play anything but Dark-RP when in comes to Garry's Mod, but I'm willing to give PERP a shot considering it was made by ZARP. Heck, I'll even try for staff If I like the gamemode
P.S Victor, I don't think it will replace any gamemode, it will just be an addition to the ones we have now.
