Any RPing - be it LARP, 'table-top' or computer gaming is nigh on impossible to get away from the cheese factor when viewed from the outside. How many times have you cringed when listening to someone enthuse their way through an RP anectdote?
In their head they are reliving the moment when their half elf Fighter/Mage/Thief leapt onto the Iron golems back and stuffed their pet Rust Monster down its gullet. In your head you are silently hoping they will just shut the hell up whilst nodding with polite interest.
We consider ourselves to be 'premier' gamers, especially compared to our lumpen colonial cousins. But I've seen enough rpg groups here in the UK to say that we arent so different...we just drink & swear more than they do.
