Battlefield Bad Company 2

This game is probably the last good Battlefield.
Tank feels like a tank
IFV feels like IFV
Helicopter feels like Helicopter
Everything on its own place - explosions, destructions, sounds design, characters audio and interactions.
Weapons feel intuitive, and customization is simple as need in combat..
Each class has its own weapons attached to it. Balanced.
It is even had some sort of modding and ai in match gameplay. The mods to BFBC2 made by 1 guy, and shared on BF3\BC2 common network of Venice Unleashed, called Project Rome.
Played VU in BF3, played Reality Mod, even played multipayer match with bots in BF4(yes, it is possible.) Bad Company 2 just better objectively.
Best BF since mighty Battlefield 2, that come out 20 years ago.
