Nexus Mods Xcom 2 Mods To Play
INI changes I wouldn't trust the mods to play nice together unless each one is changing a different. (Unless you like verifying your game cache every few minutes, which is far more of a PITA than a Nexus revert.)As for XCOM 2 mods working in tandem, it's possible that could work but if they are. Even if you know what you're doing, the fact that Nexus will revert any changes on it's own is vitally useful to anyone doing mod work. You're absolutely right about Nexus mods in that they can be manually installed but you should absolutely never do that unless you know exactly what you're doing. The gameplay will be very familiar to Long War 2 That's another thing in favor of Nexus though, you can actually look at the stuff before you install it.As I said, it depends on the mod.
All this being said, I haven't taken a real look at XCOM 2 mods but I have a lot of experience modding Skyrim using Nexus. (Obviously, since a given variable generally can't hold two states at the same time.)This is all mostly just pedantic hand wringing on my part but it might be useful to someone. If they change the same variable only the last installed change will take effect.
