Original: 1. After I had done played video game, I went to bed. ('had done played' is bad verb form) 2. After playing video game, I went to bed. (okay) 1. After I finished playing the video game, I went to bed. (This type of sentence, where "after" makes the time sequence clear, does NOT require past perfect tense.) Past perfect tense is required in situations where the time sequence is unclear. When he arrived at my home yesterday, I had just left for the airport. (leaving happened before arriving) I had already stopped playing the video game when the doorbell rang. (stopping occurred before ringing) By 9:00 am yesterday, I had already gotten up out of bed. (I got out of bed before 9 o'clock "arrived")

Don't say "had done played". The past perfect is only "had played". So: After I had played a video game, I went to bed". If you want to say "I had finished" (instead of "I had done"), then use the gerund form of the verb. So "I had finished playing". They are not interchangeable, because the first one does not say that you finished. Maybe you saved your game, and will finish tomorrow. Also, using "after" or "before" in a sentence makes it clear which action came first. So you don't have to use the past perfect at all. Use the past perfect when you want to show which action came first: "I was tired in the morning because I had played video games all night."

except for that "had done played" xD

You mentioned a good point, I think both are correct but the difference is that the second sentence doesn't have a verb, playing here is a noun and when you use a verb, it turns to past perfect. and besides it seems that the first sentence ( past perfect) is emphasizing on getting the action done or finished.
