Thank you for the reply! Yes, i was thinking at something which shouldn't be overwhelming, but still make you Plan your missions and add a layer of meaning to different armors and weapons (and maybe stats). Nothing too Extreme, but that gives the player some meaningfull choices to make. Also, it's something different to most other games of this kind. And, well, It could be something you enable/disable Just like ironman.
But probably It would be too much/too different for most players, don't really know.
