Why hasn't Slugterra ever been turned into an Open-World RPG PC game?

I really enjoyed the Slugterra series, and I’ve always thought it would make an amazing open-world game. Imagine this:

\## Open World Underground

A massive underground world made of connected caverns, each with its own ecosystem:

\- Lava caves (fire slugs)

\- Ice/crystal caves (frost slugs)

\- Jungle caverns (nature slugs)

\- Storm zones (electric slugs)

Each region has hidden tunnels, secrets, and rare encounters. You're constantly discovering new areas and rarer slugs, making you feel that your exploration. actually matters

\## Finding Slugs

Instead of just “catching” them:

\- You find slugs in their natural habitats

\- Some require puzzles, tracking, or challenges

\- Rare slugs appear under special conditions

\- Legendary slugs = boss encounters

It feels earned, not just given.

\## Real-Time Combat

\- Use your blaster + equipped slugs

\- Each slug acts like an ability (fire, ice, electric, etc.)

\- Focus on timing, combos, and strategy

You can battle other slugslingers, arenas, or enemies in the open world.

\## Modular Blaster System

Fully customizable parts:

\- Core → power

\- Chamber → cooldown

\- Barrel → range/accuracy

\- Sync Module → special interactions

All of these are found while exploring.

\## Upgrade System (RNG)

\- Parts roll random stats

\- Upgrades improve random stats

You can grind for a “perfect build” and optimize your playstyle.

\## Slug Enhancements

\- Boost damage, effects, reduce cooldown, elemental bonuses

\- Set bonuses unlock combos (burn spread, freeze chains, etc.)

Same slug, completely different builds.

\## Mecha-Beasts

\- Customizable slug-powered machines

\- Used for combat, traversal, and unlocking new areas

\## Gameplay Loop

Explore → Find slugs & parts → Upgrade → Build your loadout → Fight stronger enemies →

Unlock deeper caverns → Repeat

\## Why this would work

It combines:

\- Exploration

\- Collection

\- Combat

\- RPG progression

So basically this is a “creature-collecting open-world RPG with real builds and skill-based combat” game. I'd easily sink hundreds of hours into this game. Would you play it? What changes would you make, and what features would you add?
