I tend not to eat whilst gaming (too scared of spills really), but if I have a cup of coffee and a biscuit I do enjoy Maryland cookies (with white chic chunks!). As for why... They taste good?
Ooooh biccies yes. Custard creams FTW! If not then tthose salt n vinegar twists from tescos , pringles , pizza. all the usual nerd foods you can think of.
Umm am I the only person that just eats normal food around the house if I get hungry? :L
In fact I probably wouldn't really eat that much inbetween meals.. Maybe I need to get into this whole biscuit craze.
When I am at home I eat very little at the PC - sometimes Pizza. I am too busy knocking back Bacardi and Coke. When I travel I game a lot so forget to eat so I'll raid the mini bar for whatever food is in it, order room service for beer and tell them to throw in a pizza or burger which I demolish when I am raiding. I never eat when I do arena...far too difficult to eat pizza and heal my partner. Usually, when he dies it's like, "Mushroom and pineapple?" I leave the headset at home when I travel for a reason.....
