I liked playing this game,where i could never get into oblivion.I think the portals as a way of traveling is a much better system than oblivions,and you even get a mobile portal stone which enables you to drop it then travel to any other open portal.
I also like how you can stack weapons and spells,so what at first was a fairly weak weapon can finally turn into a weapon with awsome power,all you have to do is find or buy a weapon thet matches the one you already have then stack the new obtained weapon on top of the other weapon and you make it more powerful,this works for spells and armour as wel
You can also find or buy some good rings for increasing magic,armour stength all the values.
Got bored in the end though because i got so powerful i could take down a stone golem,or cyclops with one hit.
Horses are fairly crap when you first start using them but they do get better as your exp levels up,you can evetually kill from horse back,and they make for usefull storage when your inventuary becomes full,just drop you items in your horses inventuary untill you need them.
