Since all the Sens regional broadcasts are blacked out for me, I had Center Ice for years. Back when it was a flat rate for CI for the year, it was a decent enough deal - but for the last few years Rogers has refused to sell you CI alone, and forced you to sign up for the super sports pack ($35/mo now, I think) which is basically all the major league versions of CI. I just don't give a **** about the other sports, so it was a total waste.
Last year I got Game Center for the first time, and I was blown away by how good it was. Cheaper than CI, more convenient than CI, watched most of the games on my ipad, a few of them in my office.. Just better in pretty much every regard.
Now, I read a little while back that something had changed to allow regional Sens games to be viewed in the rest of Ontario. If this is true, I won't need to purchase anything to watch Sens games this year. But if it's not exactly what it sounds like, I'll go back to GC in a heartbeat.
