Insurgency Sandstorm is a worthy mention if you like a bit of realism, but not too much. The shooting mechanics are probably the very best that i have personally experienced anywhere - guns sound, recoil, spark, kick up dust, have ragdoll impacts, penetrate surfaces (including bricks if shooting M4/AK/higher calibers). No story mode, but SP and Coop are still excellent fun and straight to the point gameplay. Lots of maps, weapons, mods.
Arma3 can also be very simple, especially in single player - tons of single player story missions and campaigns with full voiceover and plot. Mods make it shoot close to Insurgency Sandstorm in terms of feel sound and look. Both friendly and enemy AI are much more advanced than in IS - you can order them to cover you and so on. It also has a third person mode that is better animated than Ghost Recon :Wildlands.
