@chloyster Guild Wars 2 World vs World and Ghost Recon Breakpoint (which was on deep discount). The latter appears to have been mostly turned around with regards to its release bugs but I am still in the process of gauging the capability of the enemy AI.
The fact that you can tweak the gameplay details on a scale of "the division Style looter shooter" right up to "almost mil-sim" levels is quite impressive to me.
