"Do you know how complex it is to internally simulate the creation of a computer?"
Yes, I know. You need to screw MB to case, put in the CPU, install RAM, insert graphics, plug in 20/4 power cable to MB, plug one or two molex to graphics, connect MB with disk drives with ATA tape, then plug in each drive one molex, then connect power button to MB and hopefully it's over. Simple.
After half an hour (including breaks) I've got 80% and can't get futher. I looked in walkthrough (not only official one) and done every one achievement, so I climbed second time (first time was "bad ending") to the top, and at the second step before the end, my computer has frozen :((((( NEED SAVE GAME
