So far, Namco has screwed up big time with this one, which is sad since Mr. Driller is a great series for Japan making the importers happy, but usually gets the shaft here at the U.S. The same thing can be said for this entry because when you have the online on the title and that itself is flat out broken, then we have a big problem. The netcode is barely visible currently with laggy matches as worst as some SSBB matches I had, basically it is unplayable online. Other than that, the single player and the music are the only things saving it from the whole package being an abomination. At least, the single player is challenging and getting achievement points does require some skill, speed, and luck (other than the online ones since it is broken).
Bottom line, Ikaruga is XBLA's only saving grace at this point now with such crap out in the past month. More Mr. Driller on my review soon.
UPDATE - Video evidence of the horrible online from Xbox 360 Fanboy (This is true for all online games as I noticed today myself - host gets advantage, other players get screwed).
