Which one is the fake?

I received the following letter from Atari today:

ATARI AND DEL TACO OFFER FANS LIMITED EDITION CUPS & EARLY FREE ACCESS TO STAR TREK™ ONLINE

New York, NY (January 21, 2010) Atari, Inc., one of the world’s most recognized videogame publishers, and Del Taco, the nation’s No. 2 Mexican quick serve chain, announced today a special promotion allowing eager fans early access to the highly anticipated MMO, Star Trek Online. Created by acclaimed developers Cryptic Studios™, Star Trek Online for PC is set to release on February 2, 2010 in North America.

Customers who purchase a Macho-sized drink at Del Taco will receive a free limited edition Star Trek collector’s cup and a free trial of the Star Trek Online while supplies last. Each collector’s cup will have an individual peel code that can be redeemed for a 48-hour free trial of Star Trek Online at http://www.startrekonline.com/deltaco. Customers can redeem up to four codes and receive 48-hours of gameplay with each code. As an added bonus, customers that redeem the maximum four codes will receive an extra 48-hours of access to the game for a total of 10 full days.

Additionally, if consumers choose to purchase the game after their free trial, they will receive a free Type-8 Shuttle "pet" add-on for their Starship, available exclusively from Del Taco.

“Early response to Star Trek Online has been tremendous,” said Jim Wilson, CEO and President, Atari, Inc. “Our partnership with Del Taco brings this unique sci-fi massively open online game to an even broader mainstream audience as well as avid Star Trek fans.”

“We’re excited to be partnering with Atari and the Star Trek franchise,” said John Cappasola, vice president of marketing at Del Taco. “We think our customers are going to enjoy the collectible cups as well as the opportunity to get a free trial of the Star Trek Online game.

And now the quiz: I posted two letters from two different game companies today, both looking rather suspicious. But only ONE of them is a fake. The other, as unlikely as it may look, is real. But which one is it? You decide!
