When my brother and I play Warcraft, we tend to wipe the floor with all who stand before us. This causes a lot of the people who stand before us to talk a lot of trash. I've found it REALLY bugs them when you respond politely, complimenting what they did well in the match. They hate that. They hate that SO MUCH!
Personally, I love both strips. PVP online does use shortcuts, but the strip is well written and pulls off some great gags. Commander Kitty updates approximately every 5 days, but is well drawn and reads like a Saturday morning cartoon show. I suggest checking them both out.
