Gregor mentioned this previously, but I want to vent too. Why is it that a disproportionate amount of action sci-fi/fantasy games seem to have some form of the dopiest of “fiends,” the scorpion?
Currently I’ve identified them in one form or another in:
Turok
Resistance
Resistance 2
Resident Evil 5
Guild Wars (PC)
Stupid! Stupid! Stupid!
Elf Needs Food 
Dead Space somehow managed to turn human corpses into scorpions!
And even LittleBigPlanet has a brief desert section where scorpions try to drop onto you.
At least Valkyria Chronicles had the good sense to only make you fight people — unless it was scorpions driving the tanks.
