I didn't see a thread for this anywhere so I thought I'd just mention it.
The Young Justice video game comes out a month from today. From what I've heard, it will bridge the gap between seasons one and two.
Most of the principle voice cast is expected to return. And the game was written by the show creators themselves. Both good signs.
Unfortunately, the character models are not very pretty to look at. Nevertheless, I'll be buying to support the franchise. Who knows, if the game sells well enough, maybe we'll get a DTV or something to resolve the show's cliffhanger with Wally West and to show Darkseid in action. (Most likely not, but I can dream).
