North American gamers pre-ordering Pokemon Ruby or Pokemon Sapphire for the Game Boy Advance will receive a limited edition, holographic Pokemon collector’s coin with their games (while supplies last). Nintendo of America hopes to entice customers into buying the titles that have proven to be exceptionally successful in Japan, where the company sold nearly four million units within the first six weeks at retail. The new Pokemon games include more than one hundred new Pokemon characters. Playing as either a boy or girl, gamers can battle with two Pokemon simultaneously. Both titles launch on March 17.
