The problem is, Bethesda are wedded to eternal sandboxes -
Thoughts?
Personally, I'm fine with Bethesda having their "thing" and sticking to it. Mostly because I'm not such a dedicated fan that I just play their games. I like different companies making games in different styles and concepts - it gives a variety of experiences to have, not just everything being a clone of whatever the current "In" style is.
When I want a open-world, screw-around, sandbox game, I reach for Bethesda. When I want more linear, consequence driven narrative, I go to other companies. When I want brain dead, hack-n-slash lootfest, I got for a Diablo-style ARPG. It's nice having a wide array of choices.... Beth, Bioware, Squenix, Blizzard, Obsidian - it's all good.

(That said, I had no problem with Fallout 3 having an "end" - I just played til I got there, did the Final Quest to see the ending, and then loaded up my just-before-the-end save to continue wandering the wastes. The whole furor over The End, and then having Broken Steel screw things up by making it continue, was so stupid to me. The problem wasn't that FO3
Ended, it was that it Ended
badly.)
