I love all of those games. I ordered Two Worlds from newegg.com that it supposed to be similar to Oblivion, but those fools sent me the wrong version.
I have a USA NTSC console, and they sent me a NTSC-J version of the game. Which does not work on my console, and trying to get another copy from them is a pain in the ass.
But I think Two Worlds, might be what you are looking for, despite some bad reviews, but It seems okay to me by playing the demo on the Xbox 360.
I have put in tons of hours into Morrowind, Oblivion and Fallout 3 (almost over 160 hours in F3)
But right now, I cannot think of any other games.
