Champions Online now lets you play the first zone for free! So if you want to try it out, it's a great opportunity. You can play it up to level 15. I haven't tried it yet, but it might even get you into the 2nd crisis zone.
We'll see if I can get my wife to do an account.
Also, CO is doing recruit a friend. It will net you a pet, teleporting to each other's location, additional costume slots, and a free month for extra friends you bring in. Go check it out.
