Bethesda are going ham at polishing Fallout and TES down to the bone. They should take note that when talking about either franchise large portions of the fans repeatedly state their favourite entry is never the latest. While Skyrim gets a lot of praise, sorry, it's still not better than Morrowind
Fallout 4 was far more "meh" than Skyrim. New Vegas destroys it, but that's Obsidian. Fallout 3 is still better than that and that was Bethesda.
Obviously when I infer polish I don't necessarily mean bugs. I'm referring to run of the mill quest designs, stories, writing and everything else that plays it so safe it's like generic overpolished shite Holywood will keep making movies from because it still garners average to good reviews. Basically, not many low lows, but not many high highs either. Just right down the middle. That works for many but others like me prefer the days when there's high highs, even if it means some risks fall flat in the process.
Bring in talented writers though and you'll get far more high highs than low lows even with all the risks they may take. Have a good project lead and they'll be able to nudge the writers here and there to keep them on the right track. Have a bunch of amateurs or hacks and you can bet it's tried and tested all the way to produce another safe clone devoid of creativity.
