The REAL question should be : why only by MODs ?? if they are really a success and technically flawless , why are not immediately recognized and officially applied in the main game ? Why don't companies recognize and value the talents of those who devote many hours modding without paying them back?? If these mods bring added value to the game, they should be rewarded! Companies don't want to share ... They want it all !!! TRON message is still current these days. ( sigh )
