Well, I got some Oblivion playing done in-between Kingdom Hearts II marathons this weekend.  In RPG games like Oblivion (the "do anything you want" type of RPG vs. the more linear Japanese/Console RPG) I tend to reach a point where things are no longer exciting, a wall if you will.  Yes, I could be doing a myriad of things outside of the main quest, but I find myself attracted only to the main quest and actually bored with the game outside of that.  This of course makes Oblivion the type of RPG I like, that being a more linear one.  The problem is that going through only the main quests will make Oblivion a short game.  The beauty of the game is that someone with the style I have will be just as happy with the game as someone that likes to just go off and do things for hundreds of hours.  I still think Oblivion is a really good game, but taking it from a linear perspective (main quests only) it is actually shorter than many other RPGs, including one I will be posting about next (Kingdom Hearts II).  Oblivion however has a leg up on many other RPGs though in the fact that it is so dynamic that any person playing the game can find their own enjoyment in it.
I really like Oblivion, but I also realize I am going to hit my wall with the game pretty soon.  I'm just happy to say I stayed with this game far longer than I did Morrowind.  Maybe Bethesda just made this game more accessible to the masses than Morrowind was, I don't know.  Oblivion really is a great game, but my time with it will be coming to an end soon.
