100 ways to die in skyrim
also, create a new character the opposite of what you have done before (maybe an archer, a mage, or a heavy warrior, or maybe a good or evil character), play as a race you have never chosen (perhaps an argonian, orc or khajiit), give your character a backstory and stick to it (if you create an argonian, maybe he could live in the windhelm docks, an orc in a stronghold, a khajiit with the traders, etc), do the guilds and factions you haven't done, try and clear every bounty, be on the different side of the war, try and climb every mountain, explore the very edges of the map, learn waterbreathing (or buy lots of potions) and let yourself drift down the rivers/waterfalls of the world, try and be a master criminal by having a bounty of over 1000 gold in each hold, buy and decorate every house, or just go for a ride along a road and see who/what you bump into.. i seriously can't believe that people can have finished EVERYTHING there is to do in skyrim.. for me, the game is never ending
