I am running the PS3 version. I have noticed glitches, some of which might be version specific some might be console specific and some might be even on the PC.
- When you get a PSN pop up (ex: someone logging on/off), when it's there, the game freezes for the second that it's up. If you're in the middle of combat, it's highly annoying. I do not know if turning messages off will fix it, but if it does, I recommend it. It's an unacceptable bug. This has to be at least console only, if not only a PS3 issue.
-At this point where you take a test that determines your skills, my first time through I was just sitting there waiting for the test for about 3 minutes until I had to load the game again. I don't imagine this is only an error for the PS3, because of the nature of it.
It runs well generally, and looks pretty decent. Unless they're to be patched in, there are no trophies. I could really care less about that, but a lot of people do.
So the PS3 version is no train wreck or anything, and I imagine there will be a patch for the freezing during a popup. Til then just disable the notifications and you'll be fine.
If you are completely neutral on PS3 or 360, get it on 360 - it's offline only and I think there might be some exclusive DLC.
As for Mass Effect, I just gotta say it's an unfair complaint about Fallout 3's enemies' lack of reactions. Mass Effect enemies just run around seemingly randomly, bumping into walls showing no sign at all of being damaged until they're killed.
As for the communication systems... yes, Mass Effect's is deeper. The writing is also far lamer, and the voice actors show no emotions at all. It's like they're all british comedians or something. It's possible the actual overall story of Mass Effect is better, but the dialogue and V.A. left me with no interest in it, while Fallout 3 captured me from the first scene. Also of note, I had similar feelings about Elder Scrolls: Oblivian as I did Mass Effect, story wise. It's obvious that they really upped their game this time around.
