Looks like they've made MoO3 mod picking a little easier. There's basically 3 packs, "vanilla", "strawberry" and "tropical". They all include the code patches/mods that alters the exe file too, so you really just need the latest official MoO3 patch (1.2.5 or something) and one of those mod packages. The Vanilla package is basically just a gigantic bug fix package, while strawberry and tropical both add/change things not 'bugged'. I'd go for either strawberry or tropical, but read the descriptions and see what looks tasty.
