I can play anywhere with my laptop. Usually at home but sometimes on a cafe or near our small lake we have beside our town with over 2000 people living there. The problem is that the laptop need to charge after 3 hours.
I play it from my desktop computer at home. I'm too cheap to buy a laptop and lugging one around all the time seems like extra effort anyway, so chances are I won't be playing it anywhere else any time soon! =)
