if you ignore the stupid online shit that they can't seem to get straight.
thankfully, there are people who are not on xbox live who can also play video games, sometimes referred to as "friends."
but really, this is like looking at disney porn for the first time-- it's the same wrapper for that thing you enjoyed as child, but wrapped in a modern and more adult context, so that it doesn't feel nostalgic or childish.
All that aside, the weapons, animals, the feel, the art style, animation, music...everything is pretty much dead-on. Maybe some varied animations for different weapons would help, but for brawlers, it's the equivalent of discovering cold fusion compared to the final fight/double dragon days when a punch had two frames. Since it has all the modern updates like saving, tons of characters, and tons of levels, it's way above the coveted D+D capcom brawlers and the Punisher (though those are still great today.)
I don't know why I let this sit on my HDD for a year before busting it out after people get bored of Rock Band. Best 1200 points you can spend on XBL. Now bring the hate, bore.
