[Puzzle] Video Game Quiz (solution posted)

Welcome to my new puzzle/quiz. This is similar to my previous one as it consists of a series of Youtube video clips but it has a different theme. I have spent some time digging into the history of video games to select some games you have now to identify if you accept the challenge. Selection wasn't based on my preference or knowledge about the games, but purely on how you can identify them even without any previous knowledge of these games (you can still need some background and skill though).

Prizes are from GreenManGaming or GamersGate or Steam. Two good games so far, if you solve the puzzle but you already own that game, please post a comment, it's possible I'll add another giveaway based on this feedback.

I have downloaded these videos from Youtube, cut the interesting parts and added a blur/noise filter and similar to prevent reverse image search (believe me, you can do it without using these tricks). Some games are multi-platforms, for computers and/or consoles, 8 bit and 16 bit era. Not everyone has a dedicated Wikipedia article.

The quiz was created using itstoohard.com. Please, don't reveal anything about the /puzzle/, no links, no answers, no what is gifted. No sharing, no hints, no cooperation, do it yourself, on your own. Enter the giveaways only if you are interested to play the game, Y1Bg609s not redeeming the gift will result in a ban for you.

If you wish to report any problem privately, you can get into the SteamGifts chat and PM me from there, or send a PM via Steam Forum. Don't add me, don't ask for hints via chat. I can give some hints in this thread or directly in video, if necessary. The questions have names for reference ("Q1", "Q2"...), pay attention to what you write if you post here, don't spoil the puzzle.

Q1-Q7 First giveaway (Orcs Must Die 2)
Q8-QF Second giveaway (secret)

Quiz hint countdowns start after the first wrong or correct answer (30 minutes only). This kind of hints is available only for a few of questions.

Timer (Monday 8 April, 11:00 PM CEST)

Difficulty level is variable, the first questions should be very easy, but the rest isn't hard at all probably for expert puzzle solvers like you.
