Call me psychic, but I know exactly what you are thinking so I'll tell you right off the bat, this isn't a Madden killer, however it does a few good things that even Madden wishes it could do. Unfortunately, all the new features come at a price, some of which are pretty steep.
The first thing you will notice are the player models, which for the most part are just plain weird looking. They walk funny, move their arms in weird ways, and the color of some player's faces do not match the color of the rest of their bodies. As you play the game though, you begin to notice the small things that make the game feel a little better. For one, helmets become marked up and dirty over the course of a game, and the uniforms are probably the best I've seen yet on the PS2. The uniform dirtying is especially cool to see. In Madden, even in rain games, players look way too clean, but not in Primetime. Simply put, these guys get dirty!
Player animations are okay looking, but seem to lack that certain natural (or almost natural) feel of Madden or 2K2. I have to give major points for the camera work. It is a bit overwhelming when you begin to play, but as you progress through the game, it becomes a very endearing.
The sidelines are a mixed bag as well. They are bustling with activity, but I have two major problems. One is that the coaches don't look like they should. I understand this probably involves some kind of licensing fee I could not even begin to understand, but it would have been nice if they at least kind of resembled their real life counterparts. The cheerleaders are nice, and it is great to finally see them appearing in football games, but the squads in Primetime have these creepy Harlequin grins on their faces. They look like they all used that Joker Brand makeup from the first Batman movie.
'He...could...go...all...the...way... TOUCHDOWN!'
I'll give you one guess as to who does the commentary. As with most football games (2K2 being the exception in my mind), the commentary tries, but gets old very quickly. Chris Berman and Tom Jackson's commentary is okay, but have a real canned feel to them and lack any type of emotion. It is not as bad as Madden, but it is close. The familiar ESPN music is all here, and along with the stadium music is one of the highlights of the game.
