I should bitch about HULK more: The game structures its power progression around a player's in-game accomplishments, such as "defeated 250 Enclave units" or "stayed airborne for a total of 30 minutes" or "destroyed 100 buildings" or "taken down 10 attack helicopters" -- basically rewarding you for exploration of NYC and destruction of just about anything you find. That's pretty cool.
They also limit the progression by having the higher levels of each power be restricted by story progression; the prerequisite for those powers is a combination of the previously mentioned sandbox accomplishments, and "Exposed Major Talbot on TV" or "Defeated the Bi-Beast." This is also logical and well-designed; you can max out all the exploration stuff, gather collectibles, and then take on story missions when you're ready to bump your power level up.
But in the effort to get the collectibles out of the way, there's always that moment when any Achievement whore feels that late night questioning of their raison d'etre, with the controller in one hand, a pen in the other, and a printed out map on the table against which we're checking off the stupid god-damned collectibles that EVERYBODY is putting in their games... in that attempt to clear those collectibles, I was visiting areas where the "comic book covers" are supposed to be, and they weren't there. I've got like two of fifteen of them, and I'm checking seven different item locations, so it's not like I picked them up and forgot about them. Where could they all be?
According to xbox360achievements.org, THEY APPEAR AS THE STORY MISSIONS ARE COMPLETED. What's that you say? Collectibles which, unlike all the other collectibles in the game, only show up based on story progression? So if I'm a player with NO guide, I will have combed the entire city from top to bottom for all the other collectibles, cleared them all, and be baffled why the comics are not around. Then I'll have to do it over and over again, only able to find the last Comic Book Cover when the game's main story is over?
But why tie power progression to these impossible to find items when the story progression prerequisite is already in place? Why send a player off to find something that doesn't exist, when the other items can be found at any time? Is it an intentional wild goose chase? DO YOU HATE YOUR PLAYERS, Edge of Reality, is that it?
Oh, and probably the dirtiest trick of them all: Even WITH completing the game and dealing with the late-arriving collectibles and all, the game has one piece of unlockable artwork which will only become available if you've got IRON MAN Save Data on your 360, and there's an Achievement for unlocking all artwork, so you can't get 1000/1000 in Hulk unless you've also played an unrelated game. Shitheels.
