Yes, it does bother me.
I have talked about this before on this forum, calling it the 'Vilverin syndrome', because the exact same thing happened in Oblivon with the Vilverin dungeon.
First one in the game, best one hands down, the others often cant hold a candle to it.
It is as if they purposely make the parts of the game that reviewers will see the best they can, and do the rest sort of half-arsed.
It also ensures that when playing the game dissapointments just stack up after leaving the starter area.
You never get that magical feeling back of the first few hours.
In what other quest as the golden claw one does a questgiver walk along with you to show you the way, all the while chatting?
Its a classic bait-and-switch and it grinds my gears.
I noticed you said that you don't get that magic back after the first few hours. Could this be due to the fact that you are new to the game and so the first dungeon you run into has a huge impression on you but then it wears off and the others are just meh?
Here is an example I will use. Everquest Online Adventures was a console port of Everquest. Many Everquest fans HATE that game with a passion. It is considered among many mmo fans as one of the worst examples of a MMO. Yet it was the first MMO I ever played and I loved it. It rates as the best MMO ever in my books. It was new to me, it had a mysticism that to it that no other game had (remember first mmo) and I fondly look back at it and remember all the good times I had.
Then I played other MMO's and in my book they couldn't hold the standard that I had come to expect from EQOA, why? I think it has to do with the fact that it was my first MMO so there was this magic to the game and once I played other MMO's that magic had already worn off. I was use to them, I knew what to expect and wasn't really ever svcked in by them. Maybe this is the same symptom you suffer from?
I am not trying to flame you here, just giving you something else to think about because when you said "After a few hours the magic had worn off." It reminded me of how much I loved a game that no other game of its genre could compare to despite many fans of that genre considering it one of the worst ones in the market.
