I've been playing since about a week after release and have about 1,200 hours in-game, according to Steam. I have created five characters in that time and have finished the main quest with one of them.
1. My first one was a Dunmer jack-of-all-trades type who got me introduced to the game. I got 177 hours out of her anyway.
2. My second was a Breton mage. She finished the main quest, the CoW, the Companions and got through the DLCs for the first time. She was good for 363 hours.
3. My third is an Orc two-handed warrior who I created at about the same time as the mage. He's languished, but I still have his save files and plan to pick him back up some day. He's got about 19 hours in the game.
4. My fourth is a Bosmer thief who uses archery and sneaking with daggers. She's finished the Thieve's Guild and is at the point in the main quest where she has to make the truce in the civil war. She's at the 310 hour mark. I plan to finish the main quest with her and make her a millionaire (she's about halfway there now).
5. My current one is another mage, an Altmer. She's at 233 hours with lots more to do.
