I enjoy the game quite a bit. My friend and I played through the co-op story once, which is always my favorite Bomberman mode, and I quite liked it.
I have played online and the connection is much better with the new update, just need to set options to only play people near you. If you don't change this setting, you will be playing a slideshow.
Once this game is $30, I would highly suggest you rebuy... and hopefully people will still be playing online.
