Well as far as I can see most are ~$20 on amazon now.
Only ones around 30-40 are MGS, Silent Hill and Ratchet+Clank. I can only guess that SH and RC are newer?
If you really want the game I'd say go for it although there are many new game coming out this quarter. I can see it ~30 until early...
Yeah I've scouted forums and the PSBlog and it said as long as you pay for the PSN+ subscription through the 'wallet' it should be applied to the $100 deal.
There shouldn't be a difference between the disk and the digital version. Most likely all you missed were pre-order bonuses.
I would recommend Dishonored though. It LOOKS great. I hope it lives up to the expectations I have for it.
There's also a bunch of Vita games coming out this month if...
Amazon has it for $49.99 with free Prime shipping
