Well, Half-Life 2 deathmatch is easily more fun than I would have imagined.
Devicer and I jumped into a multiplayer server, and a couple of minutes after
commenting how players were obviously obsessed with their gravity guns because
all they were doing was running around throwing things at each other, we each
caught the fever, put away our guns, and joined the fray... Pie Fight is my new
pet-name for gravity gun deathmatch, as the throwing of things is like a scene
out of a Three Stooges short. The big surprise was how insanely fast and furious
the gameplay was... the original H-L DM was somewhat methodical with slower
running speeds and people planting trip-bombs all about, but this was more like
DOOM or Serious Sam (though we didn't try team deathmatch yet, which may be more
contemplative). My favorite gameplay bit so far is getting into games of soccer,
shooting cars back and forth trying to crush each other.
