In response to post #82374963. Hi! iTZeph I'm not an expert but in the case of the question i can give you some ideas about these mod managers. First off if your happy with Nmm theres no law saying you can't keep using it. You already know how it works and all that . Heres a few bits of information about the later mod managers. Mod Organizer 1 is 32bit and aimed at bethesda games thats fallout 3 FNV Oblivion and Skyrim LE all of those games are 32bit and when you put a bunch of hi res texture mods and a bunch of pretty naked follower textures you will be doing a bunch of tricks to juggle memory cus of limits in 32bit games start doing some home work at the S.T.E.P project and look for videos from Gamer Poets Gopher and several others till you learn to use the tools available and how to install them when you set up your like loot enBoost and 4gb exe. I started when MO 1 came out and I learned to use it but if you are using Skyrim SE or Fallout 4 you should go with MO 2 because it is 64bit and is just better all around cus of all that memory it can support. Now here is the special thing that the Mod Organizers do thats so special TANNIN the developer he builds Vortex now too came up with the idea of the Virtual file system for these games. Its brilliant it stores all your mods in folders outside the DATA directory instead of dumping in the data and causing overwrites and all weird things related to load orders and gives better control when you start dumping a huge pile of mods in your game. Also one other feature he invented ( I believe) and its my favorite is the profiles. This Feature allows you to have several different versions of the same game going at the same time. If perhaps a friend wants to try a game. Or to me what is great is you can start a new game if you are trying some new big mods that are available they are as big as DLCs and some of them may be trouble prone. You can make a new game and profile for that mod group and if it blows up your other play throughs are still fine. and there are mods that don't work well or that don't play nice with other mods. And this this is my favorite thing about MO then you can go back and arm wrestle with the new mods and still have fun continuing your other game.. Now we come to Vortex Nexus latest ModManager. It also uses Tannins Virtual file system. What makes this manager special to Me is that it supports about 100 games that are not bethesda games. Therefore giving all of those games the virtual file system. This is a huge benefit for testing new mods and not destroying your present games when testing new mods. The downside is that Vortex is still fairly new and there just arn't as many videos and help specially for incorporating tools in the mod manager. I'm refering to tools like Loot, Wrye bash the Script Extenders Fnis xEdit and anything else. This is where I am stuck because I would never have been able to put those mods in a setup without the help of all those skillfull modders and those tutorials. Well i hope that gives you an Idea about what those managers do if i said anything wrong OOPs sorry but this was just general info so there shouldn't be any glaring mistakes. If there is Tannin I'M sorry please dont heetmee! Cheers and have fun
