70 hours is nothing, sorry. You haven't experienced enough of the game to make a valid judgement call.
That's like saying "I played World of Warcraft, got to level 4. I'm done. What a stupid game."
Your over-exagerated anologies are overshadowed only by your reading incomprehension...
The entire point is that there isn't much pushing you to play passed that. Sure, some people will log 160+ hours and still trip balls, but I agree with the OP:
TO ME( as in only my opinion):
- Lack of storyline outside the MQ means you feel kinda lost and pointless. There is no "goal", no "end" and no "means. I have had my optimal item set by lvl 21 (archmage robes + Maokai), and by then I had finished both the College of Winterhold's and the Stormcloak's quest line, as well as the MQ. Result? I've been sorta just "exploring" for almost 20 levels with nothing to aim at.
- Lack of quest/dialogue options and actual world impact kills the RP immersion. I cant infuse my character with a personality since there is no place for subtle elements (like speech options to choose or quest-oriented decisions to make), and I seem to be an eternal stranger in the world, even after becomming its hero ("You the new guy bringing mead?" after I become the Harbinger... "If you are into magic you should check the college of winterhold out!" after I am already its arch-mage... etc). I feel more like a generic sellsword/errand boy then a world-saving hero.
- Overall imbalance. I had to reroll my first Character after breaking it on mistake (i chose smithing and chanting without reallizing how powerfull they were). Now on my second toon, a Conjurer/Archer, and already I have been playing god mode for 12 levels. The point at which there is no reason to become stronger is somewhere in the early 30s, i'd almost say "no matter what you play". The game is unable to provide a challenge even in Master difficulty.
Alltogether im happy at the 100ish hours I have gotten out of this game including both characters, I am fully aware that most games will not allow me to play for that long. But the problem is that instead of feeling like I have finished the game, I feel like its just got boring, repetitive and pointless. There is no end. There is no reason to build a stronger character. There is no story to follow or complete. I have no impact on the world, and that world is full of clones from the first three bandits/foresworn I've come across.
Great game, but its one that leaves a bitter taste: there is no feeling of achievement/accomplishement whatsoever, and that, for me, kills the replayability of the game BIG time.
