The question of a hypothetical scenario often begins with "what would happen if...?", followed by some expression difficult to verify on the reality. Well, that is normal in the case of one of the most popular games in the history of computers: what would happen if Doom comes out to the market today? It is simple to find it out: download Classic Doom and see it for yourself.
Basically, Classic Doom is a recreation of the original, with the same screenplay and story. The difference here is that a group of enthusiasts decided to experiment with the Doom 3 engine, and gave it a renewed air to the first game in the series.
If you had never played Doom before, Classic Doom is a great opportunity to do so. If you have already experienced it, it is possible to say that anyway you will be surprised.
