the randomization aspect makes it so that all playthroughs feel different due to different spawns, weapon pickups and drop rates.
so for example one AEOD playthrough of x wad may net you a boss in map15 that gives you the black hole beam, giving you a great advantage. whereas another playthrough may just have another boss, who drops a different weapon, which maybe isn't as good. or hell, the same boss as before, but he doesn't drop it this time due to drop rates, meaning your playthrough won't be as advantageous as before since you'll struggle with cyber/spiderdemon-class enemies more.
this creates and endless feedback loop of variable playthroughs, and all that matters is that you don't mind the sheer massive amount of stuff those randomization wads have, like a 200 enemy types, 200 weapons, 200 items etc.
