Well, I have a lot stuff going on w/ my RL but I'm up for melty on fridays and weekends (w/ some exceptions).
And I'm always up for netplay from 9pm-12am, even though I wake up at 6am
Srsly, same isp + same city is most likely to result in delay 1; 2 w/ different isps, which is still highly playable, although you'll have to trade some execution for MU experience and potentially some yomi. And you always can grind some practice mode to get your exe back for RL play.
