: Incredible VR support, high-fidelity damage models, and realistic flight physics.

: It is frequently on sale for under $10 on Steam or GOG . 2. IL-2 Sturmovik: Great Battles (The Modern Series)

: Both versions go on deep sales (up to 85% off) several times a year, often costing less than a sandwich.

Depending on what you are looking for, you might be referring to one of two distinct eras of this legendary flight simulator series: 1. IL-2 Sturmovik: 1946 (The Original Classic)

: Very active servers with tactical, team-based combat.

This is the current generation of the game. It is modular, meaning you buy "Battles" (Stalingrad, Moscow, Kuban, etc.) that plug into one single launcher.

: Still has a dedicated modding scene (like the "BAT" mod) that keeps it looking surprisingly good.
