Are you the type of player that eats and drinks while playing video games? If so, what do you normally eat or drink?
I don't think I've ever played and ate at the same time. What if you spill something on the keyboard or game pad? You will be mad that you spilled food but also your game experience will be forever altered :D if you don't clean them well enough. The other option will be to buy new keyboard or game pad.
I suppose I fall in between. It’s difficult to have food and hands on a keyboard at the same time, plus generally messy. Drink is another matter. A quick sip of soda or juice between matches or spawns is great.
Food and computers don't mix at all. If you ever turned over your keyboard and shook it a bit you would see a whole bunch of crud come out of there.
If you looked at your controller in a bright light it would look like a McDonald's greasy grill. This increases the bacteria count and can make you sick.
Ever been too drunk to Mario Kart? I have. I'm a big fan of Sam Adams Boston lager and Oktoberfest. In my younger days I would have Mario Kart parties. More than one time I woke up with the Nintendo still on and people passed out all over my den. Good times.
