No, sorry, there simply isn't 200 hours worth of content in the game. In 65 hours I had fully explored/completed half the overworld and half the cities and did half the guilds. In a subsequent playthrough as a different "class" I did the other half. Unless you are fucking terrible at games or you inexplicably had to make a potion out of every fucking alchemical reagent on the world map, there's no way you should approach 200 hours on a single character.
How to get more than 200 hours in one playthrough:
1) Play stealthily on Master difficulty and don't use overpowered items or companions. If you want an extra challenge, make sure to choose a race that doesn't have any inherent magic, frost or fire resistance bonuses. Also, don't grind or use trainers in order to level up faster than you normally would. Don't use the inherently overpowered smithing or enchanting skills either.
2) Discover the effects for every alchemical ingredient.
3) Clear every dungeon.
4) Complete every quest.
5) Talk to every NPC.
6) Pickpocket every NPC.
7) Break into every house and explore every room.
8) Read every book.
It really isn't hard to get 200 hours out of Skyrim unless you feel compelled to rush through games as quickly as possible. I don't really understand your apparent disgust at the fact that people can get more out of the game than you. You're not one of those people who rushed through DX:HR in 12 hours, are you?
