Finished Dead Space 2 over the weekend.
At its core, it's basically the same game as the first. Very little has changed between games. It looks the same, it plays the same, it feels the same, etc. The weapons are almost the exact same, as well. Having played through the first game almost primarily with the plasma cutter, I did the exact same here and it still works great.
And seeing how it was set on a massive city/space station, I was hoping for a bit more variety in level design rather than the usual tight spaceship corridors, but unfortunately not.
On some level, I can't help but think of Dead Space 2 as more of a 'Dead Space 1.5'. It's pretty much the same game, only with some new content.
Despite that, I enjoyed it. Despite my apparent issues with the game being so similar to the first, I can hardly blame the developers as the first game did things pretty good. The flow of the game feels more natural than the first, the dead animations are even more sadistic (Spoilers: And even if it wasn't a dead animation, the scene at the end with Isaac in the machine with you guiding a fucking needing right through his eye was a 'holy fuck' moment), and best of all, they gave Isaac a voice and actual character.
I found Isaac's grunting and muffled yelling from the first game to be a bit silly - he's now an actual person with a backstory, emotion, and personality. It all worked extremely well with him struggling after the events of the first game. I really liked how the developers worked with his character.
So, overall, it was a pretty good game. I might just do a second playthrough on higher difficulty and experiment with some of the other weapons, since I abused the plasma cutter a bit too much the first time through. It's hands-down the best weapon in the game, so because of that I didn't bother experimenting with much else.
