What I loved in Morrowind was the open magic system - you could even fly the whole map! What I hated about it was that it was really booooooring and I never managed to finish it (got bored).
Oblivion didn't have such an open magic systen, actually they fucked up magic, it was nothing really mysterious about it, I love when game has some kind of secrets and stuff. In Oblivion I found a quest which was about some SUPERMEGAPOWERFULANCIENT SPELL and spent a few hours completing it, at the end it looked really interesting, thunders started to hit, armagedon and stuff, and finally I recieved... a spell that was weaker than the weakest one I was using! For God sake, who makes this quests?! But the game itself was better, it wasn't so boring, and with elixirs I had cameleon 120%, I could kill the guards withour them realising it
So you say Skyrim is worth buying? I was wondering if I should buy it for Christmas for my dad (who said that a gift can't be useful for me too, huehuehue).
