Deus Ex: Human Revolution is 25+ Hours Long

According to this report on CVG (via PC Gamer UK), Eidos Montreal's Deus Ex: Human Revolution is now playable from start to finish and the players lucky enough to be on the testing team have been spending at least 25 hours to achieve completion.
"So far with them playing about six hours every day, most of them don't complete the game," producer David Anfossi told PCG of the testing team's six day week.

The producer says he's also pleased with initial reaction to the depth of strategy found in the shooter, telling the mag:

"The ones that are more casual gamers, who are used to more 'corridor, cut-scene, corridor, cut-scene' type of gameplay - they play it that way for a while. Then suddenly, there's this new world that opens to them, and they start getting a bit more creative."
