I've played a few times, but I was so bad that I usually died from falling off the map rather than taking damage, even with "flying" characters like Charizard :\
One of my friends though was a Snake main and absolutely anhilliated everybody. The "ultimate" attack is just too strong...
I play tournament ruleset because final smash is stupid
Almost always I play tournament ruleset too - worse than op ultimates are the crazy items and luck element; no, I'd rather win on skill/ability alone
Also little mac is not that bad
