skeletonbow: I'm going to assume you will neither confirm nor deny it (and rightfully so), but I'm going to read between the lines of that and speculate that June 29th will be the day you hint at, and that it will be an all-bundles final encore day that also includes a repeat of the mega-flash deals as on the 1st day of the sale and June 18th, with 30 simultaneous flash items at once, and with the addition of some freebies thrown into the flash promo. I'm going to go out on a limb and predict that Banished, Omerta and the other games JMich predicted for the flash promos that haven't showed up yet will be some of the freebies offered, and that GOG will have the special game trivia contest thingie on the same day.

<grin>

Either way, I'm sure whatever you guys have planned will be a bit of fun though, whether it is all on one day or spread across several. Hopefully one of the surprises is the announcement of the pending release of LucasArts Star Wars games to the GOGalogue! ;oP

I'm picturing you now muttering to yourself things that Shultz from Hogan's Heroes might say... heheehe

This is definitely my favourite GOG promo so far though personally, good job guys!

Cifer29: Damn it so I guess it really was just my imagination :(. Oh well maybe it still will come if not well I guess I just have to shell out the 3 $ more for it.

RWarehall: It's complete. Taken from IAmSinistar's lists with generous abuse of Pidgeot's script/ I do update it by hand, but no one has pointed out any mistakes yet.

Defender's Quest with only 3 appearances is the lonely one.
Sid Meier's Alpha Centauri™ has a stellar 8 appearances (the most)

Bookwyrm627: I actually saw an error in the spreadsheet; VVVVVV is going for $0.99 in the flash sales, not $1.99 (I picked it up for that reason); I've seen it come through a few different times at that lower price. I couldn't tell who was maintaining it, so I didn't know who to notify.

skeletonbow: Not really, on the first day Octodad showed up twice at the same time. We don't know the algorithm they're using for randomness but if I were to hazard a guess based on observation it appears that they may have taken the list of all games, randomized it then they go through it and when it is passed through, they repeat that process a second time, third time, etc. re-randomizing the all-games list. If they do this, then where the boundaries exist near the end of one pass through the sale to the start of the second pass through the sale there will be a 15 game window between the two randomly generated lists where the same game may appear as one of the last 15 games from random-list-N, and also as one of the first 15 games from random-list-N+1. The anomaly would exist in this case due to the 15-game window where two runs of random games would be showing games from each individual randomly generated list simultaneously.

In order to prevent that algorithmically, the code generating the new random game list (N) would have to examine prior game list (N-1) and if any of the randomly picked titles for the new list match one of the last 15 from the N-1 list, ignore it and regenerate a new random entry. Even if they did that however, you could end up with one game going off the sale and rotating back onto the sale after 1/2/3 sale bumps.

The only way to really space out game repeats without having them have random chance of showing up close together is to generate the randomized list of games once, then just reuse that list over and over. That way every game would reappear in the sale exactly the same amount of time inbetween repeats, but then after one pass through the sale the remaining passes would be totally predictable and no longer random. It is the inherent randomness of the sale itself that makes it mathematically possible for a single game to show up twice in succession in that 15 game window in between two consecutive passes through the random loop.

This is all purely my own speculation of how their random game lists might be generated of course based on observation of what we've seen so far. I'd have to look a bit more closely to confirm it with the public list of the order games have appeared in the flash sale so far but I think I'm probably close. One flaw in my assumptions of their algorithm however is that in one pass through the game list, each game would appear once and no game would go missing from a cycle, but we have observed some games show up as few as 3 times and some others as many as 6 or 7. It's possible that some games have showed up in the sale and met pre-negotiated quotas and hit their limits and were removed from the rotation. Another possibility is that the randomness isnt purely random but is weighted based on negotiated limits on unit sales for individual games, or even day to day limits on appearances.

A bit of fun to speculate on and to analyze the data to try to estimate how the algorithm works though. :)
skeletonbow: Oh definitely, themable/moddable starship interfaces are a must Lord Vader! :)

ActuallyCarrie: Well thank you for this detailed analysis and answer:) I think I am getting a little bit impatient,,,Actually I am looking forward to the end of this sale because as someone said above, it is very addicting and it slightly detracts you from your daily routine, lol:)

txnca: I know NOTHING! NOTHING!

It is good to know that I am NOT crazy and that others hear this in their heads when it is appropriate! When I actually verbalize this everyone looks at me like I've lost my mind and when trying to explain, no one knows what I am talking about. Thank you! Thank you very much!
