Second Variety Games
It never feels like there's a lack of enemies in the room though, sure, if you look closely you might notice it but they keep the action going fast which is what truly matters. The arenas are nicely designed though, I mean I agree in that there were way too many but they had a very nice flow to them and just felt great to move around in.
Arenas violate the basic continuity and freedom of player agency in a Doom game. They also violate any sense of dread or suspense. They are a primitive crutch in order to compensate for flawed design and coding. They have no upside - at ALL, just like they didn't have an upside in retarded Doom knockoffs like Serious Sam.
