Just want to ask everyone's opinions regarding game enemies

[Ghastly]

Are too much enemy types in some mod a bad thing and would feel like it's suffering from some feature bloat?

If too many monsters do basically the same thing. KDiZD's a good example; I'd say it had too many monsters because it had five varieties "I throw projectile at you" Imps (Imp, Soul Harvester and the three Dark Imp variants. Shadow, I think, was different enough, but that could be considered a sixth). It also had four melee-only meat-shield type monsters (Demon, Blood Demon, Satyr, Stone Imp. At least the Mauler Demon could charge).

Sometimes this kind of redundancy can work. I wrote an article on this a while back with my thoughts on this. Basically, put some thought into what each monster is really supposed to do, and I think it can work.

i also dislike the fact that all of those new Imp variants are too healthy. you can't kill any of these new imps in a single shotgun blast, and that makes combat with them feel incredibly tedious, as you have to SSG them to reliably take them down.

Imps on steroids, I assume?
If there's a stronger variant of a certain enemy within a game, there should be a good reason for it. I'd suggest stating that "apart from the standard [monsters], the enemy created a large group of enhanced [monsters], should someone be that resourcecful he could break thru the outer defenses. Watch your back, or you shall be their first victim...!, and then tell the player what is so special about these new breed of monsters. Even a sentence will do it.

And of course, make sure you buy "Happy Monster" cereal in the general store. I always purchase "Happy Monster" for mine, it always makes my monsters happy and ready for a new day!

I read through that article. I say it's pretty helpful. But what if some of them are kinda similar to others but drop different loot?
