No, I would not be interested in another country/army group.
Why? because all of them feel like you’re playing the same game but with a new map.
All of the games in this genre have the same principle: Walk around, join the group, attend extremely repetitive, pointless trainings, rank up, get bored, and quit. That is if you actually choose to join the group.
On the other hand, if you choose to not join the group, the game’s principle turns into a walking simulator until you decide to buy game passes.
Besides this genre being monetized beyond belief, these games usually don’t have much going for them other than overpowered abilities obtained through ranks or game passes. (which are usually abused)
