Mass Effect 2 on Insanity took 33 hours /
An hour of that was me talking to somebody and doing the same conversation over and over again to keep getting +2 Paragon; it was glitched. I was able to keep Jack & Miranda, and Legion & Tali happy.
I ragequit because a Wraith shot a bomb backwards killing me.
I had to kill 6 Zealots while an Engineer (which was inaccessible unless I wanted to get killed) was giving them extra shields. There were no plasma pistols around and I only had 30 rounds of DMR ammo left, including the clip already in the gun.
