The plan is that everyone will be on one server using pikkoserver technology, although if that plan fails then I would assume they would make mutiple servers, not sure if they will make ones for south africa though :/
this and if the plan fails to have only one server then we will have servers everywhere where it is needed
Pretty sure it is not going to be everywhere. If the "one server to rule them all" pikkoserver fails for all, then they may try a pikkoserver in the US and one in the EU. I very much doubt we will see a server for every single continent out there. Not at first anyway.
well i just said where it is needed ^^ and since i followed the development of League of legends very close i know how fast a game can expand through over the whole world but ok i think the one pikkoserver plan will work
