The one for Amazon US is the "Butcher Street Pack" which gives you a sword fencing bonus, better "molotov" AOE and reduced damage from blasts. I haven't really looked at the other packs since the no tax/free shipping options from amazon usually edge out the competition in terms of price at least. It looks interesting, but ultimately it seems like it's an "early to mid-level" advantage at best.
I'm saving up for the Assassin's Creed 3 game for sure, and am eyeballing the AC3 Liberation/Vita Pack which is going to set me back for sure I also have to play catch-up AC2 Revelations and with Resident Evil series. I may get the Anthology since I somehow managed to skip RE 5 in it's entirety. As for the Skyrim DLC ports for the PS3, don't even get me started. It's disappointing and frustrating to say the least, but I sincerely hope Bethesda will get that mess sorted soon.
Anyone else planning to Pre-Order Dishonored? Any opinions on which pre-order pack seems most appealing?
