I don't think I'll ever actually see a game over on this side of the Atlantic, but I'm all for some competition for the NFL. Every time a start-up actually made it through that first fase and started to be sustainable, the NFL got better, as well.
Even if they didn't, they can make quite an impact. Broadcasting of the games changed drastically because of the XFL.
That said, the thing that I noticed most so far are the names. They're 25% USFL. And not even the best ones. Stallions and Express. I sorta like the Stallions, but the Express is so bland.
I don't like the Birmingham Iron, either. It's such a nothing-name. The Apollos makes no sense for a football team. The Legends is as bland as it gets and the legendarily bad headliens write themselves.
The rest is ok. Like I said, Stallions is pretty good, Commanders are decent, Fleet is really cool and I'll give Hotshots a pass. Not because I like the name all that much, but it is very meaningful and an awesome way to honour those firefighters.
That said, I do like to see how this pans out. If they can make a profit while cutting down on more than 30 minutes of commercials, maybe the NFL will have to follow suit, at least a bit.
I'm also very interested in what the "Fan engament bonus" means.
