finished the 360 version. took me around 15 hours on normal (single player, did 2 side missions).
i am surprised that i liked it much more than dead space 2. ds 3 has its share of issues, but overall i really liked it. the spectacle/uncharted moments/quicktime event overload that ds 2 suffered fom, was heavily dialed back.
they also towned down the enemy assault bullshit (hey, lets throw the player in a room with 2 respawners and tons of other enemies! lets repeat that for the last third of ds2!).
i love the weapon crafting system, i also never had issues with loot/resources. i used the bots and always had plenty of stuff (i maxed out the rig, my plasma cutter and 2 other kickass weapons and always had plenty of ammo/medipacks).
what i didnt like:
-enemies spawning behind the player without any hint/cue. its just unfair bullshit
-human enemies are no problem, but with the current controls, its just a pain in the ass to fight them.
-backtracking is a bit much. i didnt hate it, but ds3 cleary overuses a lot of its mechanics (wall climbing for example). they could have shorten the game and made it much better.
-while i like that there are less bossfights, 1 or 2 more good bosses should have been implemented.
-the story is not as terrible as some people in the spoiler thread make it out to be, but its also not great and suffers from "we need to explain shit and deliver answers that nobody really wants to know". "and we also need some pointless closure/finish the fight bullshit that is rendered pointless as soon as the credits are over".
what i liked:
-fantastic visuals, holy shit this game looks amazing. also: zero framerate/tearing issues. fantastic work visceral!
-weapon crafting is fantastic once you fully understand it.
-music is heavily "inspired" from the alien ost.
-good replay value.
