I seem to recall hearing they're basically
identical. A search for "resident evil 6 xbox vs ps3" turned up quite a number of side-by-side comparison videos of the two if you want to check them out. Plenty of comments on the videos as well, some of which may actually be opinions.
Well, yes, I did that and saw some "identical" comments and some "PS3 is clearly better" comments, so instead of trusting the divided comments of strangers I don't know, I thought I'd ask here so I could trust the comments of some strangers I do know.
