Quotes like these have actually swayed me into keeping the key I was originally planning to sell. I, personally, just couldn't get into the predecessors. I feel bad for the die hard fans , but I guess this is my chance to play and hope to like a Hitman game.
Hitman: Absolution really tried to do A LOT.
It tries to be a combo of a few different titles:
SC: Conviction -> some linear levels w/ really one way out. (there's actually a good deal of these in this game); NEW Mark and Execute skill (can only be used on some difficulties).
previous Hitman titles -> some levels, you explore big-as-can-be level w/ numerous ways to kill your main targets and numerous escapes.
Batman: Arkham Asylum + City -> One of your "Instinct" skills can let you see enemies' outlined actually through walls ((can only be used on some difficulties). Unlike Batman, you can actually see even their AI path that they will run (can only be used on some difficulties).
Hitman: Ab actually has the actual best story & characters in a Hitman title so far, if you ask me. Though, since Hitman: Ab stays entirely in the USA, it doesn't really have the globe-trotting aspect & exotic different locales that you could find constantly in previous Hitman games have.
Also, the Notoriety System and Buying/Upgrading of Equipment that were in Blood Money are nowhere to be found in Hitman: Ab's SP Campaign portion.
