Hitman (and Hitman 2) is a game of careful planning and timing. And I'm having a great time just dipshitting my way around. So far this last run, I screwed up trying to get a chef into a room so I could steal his clothes 3 times, then got seen and had to kill everyone in the kitchen, nearly getting caught, forgot to put on a disguise for a bit and got chased, carefully hid a body, but put the gun in someone's path (which I could have just carried, or paid attention), completed the last mission story for the level without getting caught (got caught the first time, because I didn't know what all of the steps were, or that I was drawing the target in) but only barely because the target's guards know what the other guards look like. Then I successfully lured and killed the other target, which apparently involved her guards standing outside, then entering the room as I was dragging the body towards the door (I could see people standing there, but didn't think about why that might be).
There were also like 3 other times I almost got caught, because I can't/don't ignore the temptation to push people off stuff or shoot every camera. Or ring the dinner bell while I'm sneaking around.
Even if I could figure out how to video my playthroughs, it would probably cause my PC to start on fire; it's not exactly a lightweight program.
