You can play all of the games from them for a one low price each month than if you subbed to each of them.

For SOE you still have to buy each of the games you plan to play under the pass, but if you enjoy many games it is a good deal. I did SOE Pass for awhile because I enjoyed playing EQ, EQ2, Vanguard, and on days I felt very bored SWG.

As for Turbine I sub to LOTRO, DDO, and would love to get back into AC on days it seems it is slow in LOTRO or DDO. If they had a pass I would probably go for it.

Hope that made sense.
