Do you prefer to play with items on, or with no items? Or with just certain ones?
I myself love playing with explosions, and soccer balls only. The results are usually quite explosive and funny as heck xD
I play with items most of the time. Playing without them ruin the idea of the game. The matches are supposed to be crazy and fun, thus playing without them makes it a pretty boring game. Personally, I think that if you can't win whilst playing with items, then you're obviously not a good player. Seriously, I've had quite a few matches where I'm just not quick enough to grab an item, a Smash Ball for example, but I still win.
I can, however, play without items if I ever feel like it or if any of my friends prefer to play without items.
