Take the excellent base game of the original DOOM and add more weapons, new levels, new soundtrack, enemies and basically everything a good sequel needs to create an arguably perfect shooter with everything being balanced and improved upon to make a even more fast paced and better experience. Often seen as "Just more of the original", my personal favorite of the two, it shouldn't just be ignored whichever one is your favorite of the two however, they are both equally worth playing for fantastic games with once again incredible mod support and you have a duo-logy of games that have became a staple of video game culture for very good reasons.
