1️⃣ PASS-THROUGH / MASHUP MODS

This is the easiest route for some cross-game ideas.

Instead of rebuilding everything, you run both games and make them exchange information. For example:

> Game A provides the world/characters/mechanics.
> Game B acts as the host
A bridge connects the two

Universal Modder has a dedicated mashup skill
- covering passthrough mods
- cross-game mechanics
- rendering/collision integration
- other approaches.
