Sigh... Why must most of the stages suck? At first I was in love with them, but as I played more and unlocked all of them, the good stages are definitely outnumbered by bad stages. The only ones I can say I truly love are Final Destination, Battleground, the MGS stage, the new Starfox Stage, Luigi's Mansion, and the Bridge of Eldin along with a few others. I just like simple, straightforward stages I guess.
The Electroplankton stage is ok for two players, IMO, but when I brought four players on it, it was bad. Waaaaaaaay to cramped.
