The game is good till you reach about level 30. Then you realise how much time you've wasted on it and think, jeez I have better stuff to do than constantly hack at a dragon, or make shed loads of leather armour just so i can get my smithing skill up.
The environments are good but after a while you don't really care for walking places as it's all the same, just look out your window if you want good scenes. Eventually you just start fast travelling everywhere, like you get a quest that in reality would take quite some time cos you have to walk there but nah, just fast travel grab whatever's in the cave and blurt. max time of about 15 minutes, try doing that 100 times, get's kinda boring.
I'm level 40 odd now and regret asking for it for a bday gift cos i'd feel bad trading it in. It's so boring at this stage, nothing is a challenge and I don't even have the best equipment. All I find myself doing is shouting people off cliffs cos it's kinda fun watching them fall down.
Not forgetting the countless glitches, and the annoying way your character kinda slides across the floor cos walking is just to uncool for this game.
yeah basically not a very engaging game after a while and you'll regret the hours you spent playing it when you could be getting some real action. I actually give it two stars.
