Silicon Knights boss Denis Dyack said hitting the level 50 limit in Too Human may take anywhere between 50 to 80 hours.
"First play through is probably around 15 hours, I guess, it depends. To get to level 50, it's anywhere from 50 to 80 hours. It's a lot! There's a lot there to want to dig! And to get all the epic loot - I don't even know if it's possible to get everything in the game, it's probably not - not for a single person," Dyack told Kikizo.
The ambitious Xbox 360 role-playing game, based on Norse Mythology and set in an ancient but technologically advanced civilisation, is finally finished. And Europeans will get the game on 29th August.
Dyack, surprisingly, then said work on the two following instalments in the trilogy was already quite far in advance.
"The story was done a long time ago," he said. "The theme of the first game is discovery, the theme of the second game is revenge, and the third game, enlightenment.
"And the trilogy and the whole idea of focusing on the Norse mythology and effects on technology we think is really going to turn people's heads."
The Silicon Knights boss was also optimistic of timely turnouts for the rest of the trilogy; it is "very possible" we will see them before Microsoft replaces the Xbox 360 hardware.
If not, Dyack revealed Too Human was built to be scalable, "So even if another platform does come out, we're not very worried about it."
