Necroscope's original Xcom LP was the first time I saw someone playing with any sort of skill. I later learned that saving every other turn, sacking recruits with bravery below 60, taking on terror missions with teams of four and stepping out around corners blindly was considered bad practice. My game improved shortly after.
Props to Necro, he's a nice guy with an equally nice voice, but he's not too great at this here thing.
