A long time ago, in the 1990s when Generation 2 was all the rage... one licensed item was a hand-held computer game that had Optimus fighting off Decepticons in his two modes (very similar to the Animated hand-held game some 20 years later).
According to a news posting, this hand-hand game is being reissued (along with a number of other ones), but 30 years of technological advances should mean that the game is likely to be a little different, either in its graphics or the plot of the game.
The original one was released here, but there's no way of knowing yet if this one will come here.
It will be released in America in the second half of the year, for US$15.
