Forever Blue wasn't that interesting to me until you said it had WiFi play! That could really be fun, group dives searching for treasure or ambushing some sea creature.
I can't even imagine what Donkey Kong Wii will be like!
As for other things you could preview or review, I'm not sure. If there were sections for them, I'd say review some Xbox 360 or PC games, but there really aren't; could start them in the Lounge.
