If you install the mobile version of Doom 3, you will see how the horror concept has changed after 17 years. The game is not at all like the ones you see now, and that is its main value.
The mobile port preserved everything that was so warmly (and sometimes ambiguously) accepted by the game's community at the time. This is the uncomfortable, unfriendly world of the game, the really dangerous skirmishes with the enemies and that special, not used nowadays approach to the player - rather tough and without indulgences.
Also, the modern player will be able to appreciate the excellent work of gamdesigners with light - let the feeling will not be the same as in front of the old lamp monitor, it is still a unique experience, which plays into the hands of the horror component.
Advantages:
A veteran of the genre will always remain one - but the game needs a new breath if it is not to be forgotten. And in the case of Doom 3, it succeeded - the excellent mobile version fully captures the spirit of the original and allows you to experience the gameplay, familiar and even innovative for its time, from a safe distance and with modern conveniences.
Unlike the last version, the balance and lighting have been straightened out here, many annoying mechanics have been fixed (even the legendary player level lighting mechanic) and the project as a whole has become a little more comfortable. The key word is "a little", as some obligatory discomfort is an integral part of this game.
It is important to note that the game is quite hardcore - especially if you compare it to modern representatives of the genre. If that doesn't scare you - on the contrary, if you want to try something with a challenge, this game is perfect for you.
You should play Doom 3 if you are:
With Doom 3 an entirely different era began for one of the oldest series, its technical and genre rebirth began - and this is perfectly visible from the first minutes.
