Just gonna drop this here and notify you folk that SC2 starter edition(FREE) now has the arcade completely unlocked. So you can play all the races, pretty much everything and anything except the campaign. You still need to pay to play the campaign.
That's actually pretty radical, because I hated the campaign.
...Anything but the campaign?
So, ladder?
Skirmish?
Patch notes.
Your answers are there. I think if arcade is allowed that ladder and skirmish are as well hence the clan additions.
Wow, they're getting kinda desperate. First they made everything but the campaign free if they used the invite-a-friend system, now they're making it free period. Still... Cortex is still out there.
"That sucks! I wanted Starcraft II specifically for the campaign" -- no-one ever, throughout all of time.
