Let's be honest: It looks like 2003. The 3D models are blocky, the textures are low-res, and the menu UI is a clunky Windows XP-era spreadsheet. Even with mods, the base lighting is flat. Do not download this expecting 4K HDR ray tracing.
It is important to address the legal and logistical status of the game. The game is technically "Abandonware." This is a grey area in copyright law. The original publishers (EA) and developers (ISI) no longer sell the game, nor do they provide support for it. You will not find it on Steam, the Epic Games Store, or GOG. f1 challenge 99-02 download full game
