Everyone, please chill out. I just explained this in three other threads so I'll do so here too. Yes, Xur really is powered by a random number generator program in the engine. But what everyone here is failing to understand is what is the definition of Random, [b]as it pertains to a computer[/b]. Yes, we all know the definition of random as it pertains to physics (See OP) but in computers it has an entirely different meaning (http://en.wikipedia.org/wiki/Random_number_generation#.22True.22_random_numbers_vs._pseudo-random_numbers). The reason someone has been able to "predict" Xur's inventory is very simple, they cracked the RNG seed of the game. If you have the seed of the game, you can very easily take that information and plug it into any old C++ program and run your own generator. The output numbers are then translated to item ids and voila, predicted inventory. Yes, Xur is Random. The only "loss" of "randomness" is coming from the fact that someone knows what the seed is. The only reason for the changes came with the addition of DLC which expanded the bounds of the computation to include the new items in Xur's table. End of story. There is no conspiracy, and nothing being hidden from you. [b]Edit[/b]: Common Conspiracies that are disproved by this notion: [b]* Xur's Inventory Is Generated a Day Before Claim:[/b] Yes, it's entirely possible that the inventory is generated one day before Xur comes to the tower. If you hold the RNG seed of the game, [b]or know how it's calculated[/b] then you can just as easily take that information and run the seeded calculation in the future point. The pseudo-code of this notion is easy: int seed = n; //<- Game's RNG Seed foreach(items as key => value) { int itemID = rand(); //<- Modulate by min & max ids } If you know what the seed is, or can accurately predict it for the time when the inventory is generated, you can match the calculation exactly. [b]* Xur's Inventory Is Known for x Months Ahead:[/b] See above, if you know the RNG seed, and the seed is "constant" IE, does not change mathematically, or can be predicted at the point of running continually, then you can predict the items with a 100% accuracy for as long out as you desire. [b]* Xur's Inventory was "modified", new items were "added":[/b] Then why was there no accurate predictions for that week? Easy, the seed and modulus for the values was adjusted. This happened right at the release of the DLC due to the addition of the new items.

Xur's sales list in order: Take note of the pattern in bold. This added with Deej's video that he says Xur is not random and the Developers have a plan. Xur is NOT random, and if Xur is a lie where else has Bungie lied? What else is not "Random" as they claim.

Who cares really? I'm glad he is random. So you cry babies don't always get what you beg for.

It's obvious he's not bc some one predicted his inventory flawlessly from heavy ammo to armor. So very obvious to say the control him and set him up 100% so this game is not all rng.

People have been able to predict Xur's loot weeks in advance. It has never been RNG....

Guys, Xur is RNG. However, he already randomly has everything laid out for weeks to come. That's how people know. Now, Bungie CAN change his inventory. So I don't know if you'd still consider him RNG, but he does randomly generate his loot, however, Bungie has the power to change it at will.

WHY DOES IT MATTER?! It will not change anything, if you want exotics just play the game.

Proof XUR is not Random at 1:04: http://youtu.be/YLxHKQA-Eew Although there was post that came out from Deej within a couple of days from this vid saying that Xur was random. To me imo, it sounded as if Deej blew the whistle on Xur not beinf random. Later on the forums, he recanted. Now imo once again, I felt like he recanted because when Xur has stock that the majority scoff at, the devs don't want to be blamed for it. After the flack that this game has taken even though it's extremely popular, that's one less thing for which to cast blame aside. Perhaps a better way to sum it up is that Xur's inventory is manipulated with different percentages for each exotic item. Bounty items are not included (I think). Items like Gjallarhorn, Thunderlord, and Hard Light have lower percentages to appear. Hell, for over half the community, it's hard for those three to appear from a random loot drop. Other exotics are tweaked in which they have a higher chance to appear. It's a psychological edge the devs have because they incite insane passion for this game from all spectrums. It creates board chaos good or bad. And by them saying it's random, it generates a longing to see what's in store for Xur next week.

All of you kids are so oblivious. Prior to the launch of the game. Bungie blatantly stated that they would be dictating his stock. So you can thank them for every week you don't get heavy ammo, every week they sell no land beyond, and every week they compensate for all the Snowflake they suck at this game. I honestly don't care what he sells besides heavy ammo. I already own every exotic.

Megaman (Nostradamus) leaked again, he's gonna sell this next week..
