Not really, just go look on steam at your play time. Unless all your doing is idling, then it's fairly accurate.
I think you get my point which is why i was saying when you get into the mud of things with all things considered it often it's just as easy as that. you don't have a game with 1k+ hours played because you didn't love it.
Now, if you have one game that has hundreds to thousands of hours more than any other game, you probably enjoyed it a lot. Though I have read a lot of players really regret the amount of time they spend on games like WoW or LoL.
