Hmm, thinking about it, I'd say No. My experience is only with MW, OB and SK. All are good and bad, but when it comes down to my number crunching; MW most hours played, Skyrim the least. OB needed modding the quickest to fix it's crazy levelling, then it became much more enjoyable, I think I actually completed MW before I got into modding it, while Skyrim I guess I'm halfway through the main quest.
As to the quest lines, I was totally hooked into MWs, once OB was modded to sort out the levelling, I also found enjoyable, but Skyrims I'm finding more difficult to feel interested in. Apparently there is a civil war going on, and if I wanted to, I could join in and pick a side. But I've not felt inclined to do so.
Comments about levelling I find amusing. All the games are levelled to the character. In MW this was just creatures, but you had new creature models at higher levels, not just the same thing with better stats & gear. In OB, you just had a bandit that levelled with the player, and had access to all gear. In Skyrim, enemies are commonly put into level bands/ranks, and have a restricted armoury, but to "balance" things, at higher ranks, they have greater reserves of health. So basically, Skyrims common enemy encounters are just as levelled as Oblivions, but they cap at certain levels of stats and gear.
In my mind, each following games open sandbox has gotten a little smaller, with less sand and more covered up. This is the "streamlining in game design" that is going on. It's slowly drifting from the RPG style of the older games, to something new.
Personally, Skyrim didn't reach my expectations, I thought they would learn from the errors in OB, and focus again on stats and the like, but they took a different road. The next TES game might carry on down this road, or might take a sudden U turn, or head in a totally different direction. Only time will tell.
My suggestions for future are: Less voice acting, get levelled lists more randomised so that no 2 games are the same (every game I'm modified item and creature lists for more variation/randomness), static and uniquely named NPC enemies like in MW, spellmaking, the missing spells, enchants, perks (if they are sticking around) not so overpowering. In all, make the base system much more open, let the players use or abuse it, it's just single player, so no real need to restrict us just ensure some things are not just blantly abusable (100% reductions in spell costs, smithing, etc).
Each to their own though, this topic has been an interesting read with everyones opinions. Time though to get back to the Skyrim CK and see if I can get the damn thing to do what I want it to do
