The mega mods are a compilation of various mods. Sobers list is just that... a list of mods you need to install that makes up his Mega Mod.
There is no "all in one" mod, like GWX for SH3, that you can install for SH5.
You can however install all of the mods in Sober's list, or ones from it that you feel will improve your stock unmodified vanilla SH5. Various member's have lists they use that they've posted that you can also try. It all boils down to what you think is best for you.
BTW... if you find a recent list by me, it was a test that I tried and it didn't work quite right....pass on it.
To install your mods go here and download Sober's MEP file.
http://www.subsim.com/radioroom/down...o=file&id=3492 He has a great explanation of how and why a MEP file is used, and how to use it. If you don't use all of the mods he has listed you can edit it and install those that you want. But make a copy of his and edit that one.
