Yeah, I'd highly recommend the game to anyone, hockey fan or not. They've made some awesome adjustments to the game (starting back in 07) and it's only gotten better.
Do they even have online co-op seasons yet? Not getting a new one until they do.
Online co-op seasons? I don't know what you mean by that but the thing you + moron would be interested in would be Online Team Play.
Basically, each player controls an individual on the ice, you can have up to 6 people per team (one per position, obviously). You can form your own team and you'll be in the league, your teams record and stats as well as individual stats are kept also.
