Vault in New Vegas have more creativity than the average Vaults in FO3
Jungle Vault Blue Gas Vault
Red Vs Blue Vault VS Musicians Vault
Voting Vault Gary Cloning Vault
First match up, The Jungle Vault vs the Blue Gas vault. Ok to me this is the one each of the fallouts put effort into that didnt relate to the main story. The Jungle vault was a vault thatwas doing an experiment on agriculture, I believe someone got sick was the first indication that something was wrong. A fungus attack the lungs and began to grow there essentially taking over the host after he died. This spread to others and the plant life got out of control taking over the vault. This is a neat premise and they could have put a lot more effort into it, aside from story all I saw were monsters and foilage. I saw the mutants and the plants that attack you but nothing else unique about the vault. I had Cass with me and I just kind of opened doors and explored while she shotgunned the hell out of anyone coming after me. No super boss plant, no like chemical weapon, no weird moments just that. I was expecting much more. For example the Blue gas vault was actually kind of neat, you go in first greeted by crazed vault survivors and you think woah what is going on here. Then as you go in you start hallucinating and seeing your dad, then there was a sequence where you are in a corridor and all the computers are on while everything is blue. Then you have to fight that guy and you have to fight the Tunnel snakes and it was really just an expirience like what is going to happen next, why are these guys crazy and whats goin on. Jungle Vault seemed like a standard dungeon with a backstory it didn't feel like an experiment that drove everyone mad, also I don't think you can contract any spore sickness where as the gas in the Blue Gas vault effected you too.
Red Vs Blue Vault Vs Muscians Vault. The purpose of the Red Vs Blue vault was to test the effects of grouping similar individuals into seperate groups and seeing the result, almost kind of like that one psychological experiment about where the Prof put his students into two groups (guards and Inmates) to simulate a prison enviroment at a prison. Apparntly people got so into their roles that it had to be stopped. In this case sulfur poisoning and undetectable noise was involved. This drove everyone mad and I suppose they may have killed each other off. In the Musicians vault it was an experiment using white noise and hypnosis to try and trigger people into violent soldiers that could be used as super soldiers to conquer the wastes, however it backfired after a lot of killing, and the experiments gone wrong. The overseer was on a power trip to get the mission done so much he killed his head scientist to proceed with the experiment. Now I was only briefly in the muscians vault once ever, but I remember the Red Vs Blue vault as being a not so bad vault..IF they used it to its full potential. I read a lot of the peoples thoughts but it felt so distant, like as if I read a diary about what life was like during the American Revolution, there was little or no connection between the events in the present and no definite answer as to what happened. Apparntly the Muscians vault had a civil war and was bobby trapped, very interesting in my opinion but since I can't remember it well I will leave this comparison for you to decide
The Voting Vault vs the Gary Vault. I believe these two should be compared mostly because they were the second greatest effort I saw in a vault. The voting vault had cheap posters up on the wall (to be honest I could think of something better slogan wise) and the Posters really didn't measure up to anything like the "Lend Uncle Sam a hand" or "Join up stop the Red menace" posters and billboards of Fallout 3. Anyways so then when you explore the vault you eventually find your way down to the room and the room with computer was there, you fought some robots after watching the movie and then got to read what the comps response was to them wanting to end the experiment. At this point I had a smile across my face, this was what I was waiting for the entire time exploring New Vegas Vaults, it was the promised dark humour of the Fallout world, it was the tragic irony of the experiment and it proved that humans would rather die accepting something as inevitablity instead of challenging it. This was the hallejuah moment of the Vaults in New Vegas, but it didn't save the Vault. The Vault seemed cheap, petty and the story didn't seem to work as to what I would imagine a group of 1000 people in the scenario would accept. Corruption from one big party, I can see that party being thrown out of power fairly quickly and a lot of the vault lacked when there could have been so much more. Now the Gary Vault in comparison was simply the opposite, it wasnt the dark humor of the Voting Vault, it was almost comical. It had a bunch of clones calling out Gary! as they would attack you, this vault had however an interesting grab that pulled you into the story. It was like what are these guys and why are they here. The vault was about trying to deal with human power conflicts and somehow cloning Gary was a result, They even stated that they were planning on getting rid of the Gary's but I guess the Gary's won out in the end. This vault made me want to explore it. The Voting Vault only impressed me at the end, and it only impressed me because it was like gold compared to the other NV vault experiments. I felt like I wasted time in the VV but the ending sort of justified it. With the Gary Vault I had no concept of time I was having a blast.
Also I played through all the Vaults and the New Vegas vaults seemed dull in comparison. To be fair they had good ideas but they never expanded on them, they did the bare minimum. The Fallout 3 vaults had good ideas and were "good" they made me want more. But in the New Vegas vaults the word fail regularly came to mind.
