Well, the game itself has been out since 2011 and by now I have played it back and forth too many times to count, new skin, better looking graphics, blah blah blah etc., all worthless.
What makes me come back to it is mods, especially the ones from loverslab and nexus. I think I have around 800ish right now on my HD and 400ish on my current install, my ESPs alone are almost maxed out at 238.
To me, its very simple. If this remastered version breaks the mods, especially the up-to-date major ones, then its not even worth the download, free or not it will end up being nothing but headaches and frustrations. On the other hand, if going to 64 bit improves it all by eliminating the 4GB limit and makes the game more stable, on top of the other eye candy, then its something I can definitely hang with for a long, long while to come.
Even though Bethesda says it won't break mods, I'll believe it after I see it and hold my judgement until then.
