I thought I would just like to mention this game as the new official Smash game will soon be released internationally for the 3DS. A new version of
Super Smash Flash 2 has been released, and it now includes
online multiplayer. If you don't own a 3DS or Wii U, and you been dying to play a Smash game again with your friends, this can be the perfect
free substitute for you for the
PC.
I tried out this game for a couple days, and I will say that it actually felt like I was playing a real Smash game. All the characters play decently and some of the stages look alright too even though they are all pixelated.

Here are a few videos you can look at, and the current character roster for the game:

Sure, there is like three 4th party characters in there, but its not like you have to play as them if you don't like them.
