Those who played Wolf3D surely remember the greatness of that game and when Doom was eventually released, the graphics seemed unbelievable to me. Unfortunately, the opposite applies to people who have played more modern games before playing Doom2. Simple, effective and provides all the goods. I love first person games. DoomII has alot of diferent monsters and levels too,and they get harder and harder.
Monsters are actually smart and sometimes even attack differnt kinds of monsters.
People who dont like it are just ametures who cant beat it. The monster are cool and seem to be more intelegent than other games. They will kill other monsters if hit by them, but not the same type. There are different skill levels and, as you beat levels it get harder and harder. The graphics arent as bad as most people say and i think they,re very good.
