There should be a consoles section at the top like the games do.
But I beg to differ! Sure, the Wii is old, and a lot of the games on it are for the younger ones, but there are many good games for Wii. Especially first-person shooter games on Wii. Plenty of people trash-talk Wii because of its graphics, and yeah, they aren't amazing, but the game play is a lotta fun.
Try out Conduit 2 and Goldeneye 007. Great games with online multiplayer :P
