It didn't take me 150+ hours. In total, for 990GS (only need the coop achievement) it took me ~60 hours on my cyber commando, then ~6 hours (guessing) on my human berserker, then another hour or so for each of the other classes to get Jack of All Trades.
So in total for essentially everything, I would wager about 70-80 hours of gameplay. But if you dont want the elite set, then you could probably drop 40 hours off that.
I will update tonight with exact times.
...and here they are
Commando: 64 hours, with full elite set
Berserker: 8 hours to do full game (killing Hel with Human character)
Champion, Defender and Bio-Engineer: 4 hours total to do Jack of All Trades
The pain, the torment and torture, profanity, nausea, suffering, perversion, calamity. You can't get away.
