I'm going to delete the descriptions for both mods until I understand exactly what I don't understand, haha.
EDIT (after reading your edit): Oh! So it's basically widening the range of difficulty while still spawning creatures based on the player's level? I'm over here assuming it's like a place-centric overhaul and doesn't do any scaling to the player's level. If it's actually similar to the vanilla game in that the challenge is always the same as you level up, except it happens to spawn tougher/weaker encounters compared to what you'd face in vanilla, I may actually want to use it in my current game! I'm probably just an idiot, and taking various things I know about an FCOM setup with MMM and OOO and everything combined and applying it to MMM alone. No wonder I couldn't get to an agreement/understanding with Psymon when I am TOTALLY WRONG, haha.
