The fjords is another map about the size of Broken Valley, and there is an island about the size of the starting section of Broken Valley. In the city Aleroth, before the Hall of Echoes there are limited places you can go; afterwards (the FoV section of the game) the city opens up a bit. IIRC the official playtime estimate for D2:ED was 40 hours (I explored everywhere, etc, and took 75 hours), while FoV was 20 hours, though the combined DKS package was also promoted as 100 hours (Larian estimated the minimum playtime, while the publisher went with more of an average).
At least in D2:ED there was a technical level cap of 60, but you are not going to get that high without using a trainer. I think the typical end game level is in the mid forties. I have not finished yet, but at the end of the D2:ED section of the game I was level 37, and could not have reached level 38 without taking advantage of a couple respawn points (in the original release of D2:ED several people made it to level 40 doing that).
