I'm pretty new to the Playstation club, but upon the advice I saw on this forum, I did signup for the Plus membership.
So far I'll say the advice was good. I've already downloaded several games I actually was interested in, and some of the discounts have been alright too (already it's immeasurably better value than the xbox gold account I also have - my standard on what a premium service ought to offer has now been raised, and I don't think I'll be renewing that one).
My query however is how often the instant games and member special prices rotate. I get why they don't tell you how long things will last for, but it would be nice to know at least from patterns in the past how often new things will show up for downloading without needing to log in and check the slow loading storefront. I find myself reluctant to want to buy some games like Journey. pixel junk, or fl0w, just in case they ever make an appearance in the instant games collection list, so I was keen to hear other peoples thoughts on that too.
