Counter-Strike I honestly don't care if it works well or not, because when I do play online I usually get shot into oblivion by someone in a third world country. It does work much smoother though, so my n00bness can no longer have the "lag" crutch I used to use.
Smash Bros would never let me on a wifi match because my connection would always "time out" or something. Now it only does this 70% of the time, and there is little lag in the actual match. Sometimes its noticable, but it usually isn't a big deal. I can finally pwn people from around the world. In my matches today, I have been averaging about 2nd to 1st place in my matches. I don't like to brag, but my Brawl techniques are pretty good if I do say so myself.
So now I am looking for people to play with. Offer me a challenge and I will accept assuming I am not working at the time. I look forward to cleaning the floor with your characters soon :D.
