For each of the 'game complete' achievements, you need to start from 'Prepare to Drop', otherwise the game doesn't count the game as completed because you didn't play from the 'start'. It's exactly like Halo 3 in the respect that a cut-scene counts towards the achievement, and if you want it, you have to watch it.
50K achievement: Gears of War 2 - Veteran Gear (75G)
100K achievement: Wolfenstein: The New Order - Uber Hero (50G)
