'Star Trek Online' is a hit with Spock

— -- The Star Trek Online game has the approval of none other than Spock.

"It's very intelligently executed, but most importantly, is authentic to the whole Star Trek world," Leonard Nimoy said Sunday before helping unveil the game at the annual Star Trek convention in Las Vegas.

The massively multiplayer game, from Cryptic Studios for Windows PCs and perhaps Xbox 360 or PlayStation 3, takes place about 30 years after Star Trek: Nemesis. Players can captain their own starship, as a human or alien, as they seek out new civilizations.

"They have actually been playing this game for quite a while on Vulcan," Nimoy quipped. (Humans will have to wait; no release date has been announced.)

Nimoy says J.J. Abrams' Star Trek film, due May 9, is "going to be spectacular. I'm told that the studio had a first screening about a week ago and are quite thrilled."

In the prequel, Zachary Quinto (Heroes) plays a young Spock.

"We actually have a scene together," Nimoy says, "which is quite special. We meet coincidentally in a time crossover."
