that was the great thing about the game, it was spooky and somewhat unpredictable. I think I read somewhere that they programmed the Necromorphs to spawn behind you 30-50% of the time.
You didn't say what you thought was "sloppy" about 3, but after reading this response I can only assume you felt it was too action oriented for a survival horror game?
The only slight nit pick I have about 3 is the love triangle dialogue got a bit immature and tedious, and you couldn't play all missions solo, but that was less than 10% of the game.
The game being more action oriented than the first two made sense. Even the writer of the first game said this, and that continuing to have the game world in one ship would have stagnated the series. It also made sense, as he said, that the outbreaks would increase, which of course means more action and better weapons needed.
Many love the first game for it's horror, but much of it comes from cutscenes and traps (enemies spawning behind you), but that is really only "unpredictable" first play through. I mean all 3 of the games had multiple jump scares. The only one with real replay value was the 3rd, because it took a while to learn how to best craft weapons, and where to find the rare parts for them. I also wasn't bothered by the universal ammo, because there was still plenty to think about, and it made inventory management easier. The first game is also very easy to play, even on Impossible, using just the Plasma Cutter all the way through.
I really feel DS3 was unfairly bashed and it SHOULD have sold well enough to continue the series, in fact some argue it did.
Oh, BTW, forgot to mention I really liked the Mass Effect series. Of course Andromeda had it's problems, but rumor has it they're still keeping the series alive, and may even be working on ME5. That said, after ME4 and Anthem bombing, and EA letting go 350 employees, you have to wonder if there will even be a ME that matches the first 3.
I also feel I have to mention that there is a semi confirmed rumor that 4A Games, makers of the Metro series, have been developing for 5 years or more, a new FPS Space project, so that could be as good or better than Dead Space.
More evidence has been found that suggests 4A Games is working on a new IP set in space.
