Ugh..... I never thought me of all people would have to give an english lesson.
Gaming= the act of playing a game.
Gamming(pronounced like gams)=the act of talking
Gamming it up is what two old bittys would do. They would be gamming about the latest gossip.
That concludes our lesson for today. I hope you kids took notes there will be a test next tuesday.

p.s.
Social intercourse is a smart way of saying interacting with people at a socially acceptable level. In other words talking and gossiping ect... You guys disgust me sometimes.
So dude you need to change the spelling, or else someone with a decent level of education is really going to make fun of that slogan.

Artwork looks great though. Personally I would ditch the text all together. I've never seen a real arcade cpo with that much text on it. At the most they have the logo to the game in the center, which might just happen to have text on it. Also the logo is usually much smaller than that. Remember, you want the cpo to blend in a little so it isn't distracting from gameplay. Your marquee and sideart are the pieces that are supposed to be the attention getters.
