War Thunder
This game is one of its kind. Let me tell you several things, that enslaved my heart right after I learned them:
- Its community is amazing. You almost always get an answer straight away, even in-game.
- Graphics are REALLY good, considering the maps' size
- No pay to win - you can get additional stuff for real money, but it doesn't make a huge difference in-game.
- IT'S FREE - need I say more?
