Ok, after one beats the main quest, is one supposed to just run around and do other ones? What if....one has beaten all the quests they can possibly find? Is there some other big important thing to do, or does the character just get old and die, or do you just raid caves forever? If...someone could help me out, that would be cool. All the guild/group quests: check. Arena: check. Main quest: check. Wandering around looking for inns and towns: check. What else is there?!

hmm......... try doing all the master trainer quests, the daedric shrine quests.... and .....
buy all the houses! lol just throwin out ideas...

Hehe. That's cool, thank you. I did the daedric ones, as well. And...bought the houses. xD I'll just try to keep leveling up and see what happens.

Run around and kill all the villagers so you own Tamriel.. or at least Cryodill...

O_O Uhm...cool. xD I've killed cities all at once, but never the...entire country...

Find the emperors hex number thing and make 1000 of him

1000 emperors: FIND HIM! AND CLOSE SHUT THE JAWS OF OBLIVION!

Thats scary... How about .. ummmm.. ummm... ... I got nothing

Wait....what emperor hex number?!

Start Goblin wars. Those keep me amused.

Um... get all the doomstone powers... the ones you get as your infamy/fame goes up...

Pretty sure you have to have a total of 70 to get the highest one. When you get them all, with potions, you should have around 700-900 magicka if you are maxed... That alone gives me all KINDS of ideas...

Make your own spells....

Make a new character and play using a different style. Try being "evil" or "good." Try kill a Lich in one hit... Try kill a Lich with a silver dagger...

Um... try beat all the quests before level 20, try max your char out to level 50-52 (the highest level possible with a specially created character is 53-54 or something like that, and you have to really mess up your skills)

Talk to everyone......

When all this fails...

DOWNLOAD MODS!! Mods are the BEST!!! Because of the WONDERFUL modders, Oblivion will NEVER END!! YAY!

Some ideas...

Cadaver

Well once all quests are completed I think the game is designed for you to simply stop playing that character and start a new one. Try one pure evil, or one pure good, only joining the evil/good factions. Should be an interesting change instead of running around doing 'nothing'. See how you get along if you have 100 infamy points and 0 fame points and everyone's attacking you... (if that is possible).

Anyway I envy you for wanting to play the game for so long. I got fed up even before I did all the quests. Hope I'll get the urge to play again soon though.

You find it out in the CS..Find the emperors character in it then keep your mouse over it. And it should tell you.

Hahaha. Thank tons for all the ideas. The new evil/good character thing is keeping me going. I'll have to do the doomstone ones. Thank you aaaaall!
