So... where in my savegame can I see how long I've played (strictly net, not gross)? Because there's only the real time of the respective save in the file.

So I wonder how certain reviewers can tell the game is 24 hours long, if there is no proper hour glass? Or is there?

They probably have not beaten the game and rushed maybe one chapter of the game and gave an estimated time by multiplying. I think the game will take me about 100 hours to complete once.

They said 24 hours for main quest, with some side quests not played. But I guess they didn't read anything in the journal, played on easy and didn't need any alchemy or crafting. So I'm not worried that the game is as short as they make it out to be (ironically, they also mentioned, it was a LONG game).

But I still want to have a timer. Come on, even DA2 had the play time in the savegame descriptions! Do I have to wait for a savegame editor, that might be able to read that information?

100 hours? That would be insane. I have no clue how long it took me to beat the game, but having done practically all the side quest, I would say it was around 25 hours. And I read the journal, crafted items, etc...
