Well, Oblivion wasn't as bad as some people here may say. Of course, it lacked depth, story and characters and the combat was boring (oh god damnit, I hate those goblins. Especially as a highlevel character. They take so many hits!) .. but it entertained me for a pretty long time. Alright, probably just because of the user-made PlugIns.. they were awesome!
Soo, long story short, I have my hopes up for a worthy successor of the Fallout franchise. If it's just Oblivion with guns.. I will probably send some hatemails, flame fansites and end up buying the damn game anyway, hoping for a big user mod that turns it into a somewhat real fallout game.
