According to the monthly newsletter it seems like GA will be free to play except if you want to engage in clan/alliance gameplay.
Whether or not this will divide the scene significantly or just be a great way to keep playing - even if you've spent all your cash on beer and women - remains to be seen.
We'll also get a free month with the purchase so that will be a good way to try it out and see if it's worth paying the extra riksdaler for.

Global Agenda: Conquest ($12.99 per month, $11.49/mo for 3 month, $9.99/mo for 6 month) includes: * Access to Alliance vs. Alliance (AvA) World Domination gameplay

As you may have noticed, it says that you can play "through 30 levels" on the free side. We asked Todd specifically about this and he reassured us that the max level of 30 (which has not been announced prior to this) is in effect for both the free side and the sub side. In fact, they made sure not to hinder essential gameplay mechanics on the free side, and this is just an example of that. Some of our other concerns focused on the balance between sub and non-sub players. Yes, a non-sub player can join an agency with subbed players, with the option at any time to sub-up to join their friends in battle. Yes, subbed players can join their non-sub friends at any time in the instanced battles.
