[ENDED] [Puzzle] Nostalgic PC soundtracks quiz [WITH MANY HINTS NOW]

QUIZ

To keep it shorter than always:

• Prize: Nexuiz (2 copies)
• Ends: Oct 20, 2012 05:00 PM CEST (but after winning give me about 24 hours to send - I can't predict if I will be on PC on this exact time)
• Answers are game titles. Games are generally from 90s, and every was released on PC (DOS/Windows).
• Rules as always - don't share answers, hints, giveaway link.
• Hints are built-in and shows after one hour. After some time, I will decide about giving more hints, and maybe I will post some as answers in the topic.
• Gifts will be send by e-mail.

Good luck!

EDIT: It's 12:00 AM here, and no solvers, so I think it's nice time for some hints:

• 8 is somehow related to Bulletstorm.
• 20 is last good installment of very famous adventure games series (with "missing" one part).
• 1 isn't a game about killing, but hey, dying is an integral part of it :) .
• these Youtube uploads aren't by me, so why don't you look more closely at them?
• one hint contains game title, and few makes finding game title too easy with Google.

EDIT2: I promised hints if there will be no solvers, but it appears, that there is one solver :) . However, I will give some more hints, but not for all questions:

• 14 was made by a company, which has been sued by Sega in 90s.
• 2 wasn't made by Sid Meier, despite the fact that...
• 4 was meant to have 3d sequel, but development has been halted
