I'm late to the party on this one: I picked up my LE on day one, but was busy with school, work and other more important things until this weekend. I'm just now getting into act 3 after a 9 hour marathon.
I can't tell whether I like it or not: I'm enjoying myself moment to moment, which is always good, but I don't know whether the overall experience will leave me with a positive impression when I'm done. A lot of what I found endearing and fun about the first three games is pretty tired by now. I'll have to finish it next weekend before I reach a conclusion.
While we're at it, the LE box is nice and all, but I probably could have picked up the regular edition without pain. A blu-ray and gimped soundtrack aren't much for bonus materials. And we all know the greatest hits version will have a ton of added crap anyway.....
