those green guys. Believe I discovered them both, by going to Joe's and asking for about ten $1 chips. Got back out to the truck and saw the manufacturers' marks were different. I had never seen the GO mark before and had no idea what it was - looked like a numeral 40 or something written in Chinese. I did some online research once back home and also "discovered" the Game-On company. Never knew why chips were made with both marks, my only guess is that halfway through the order, CI was discontinued and GO took over making the balance? Those may be the first chips on which the GO mark appears. Very strange and green in keeping with the Alien theme of the convention! See you guys there Thursday morning!
