I need to scope this down to an MVP. This is a complex game with many systems (mining, crafting, building, farming, combat, survival, day-night, weather, biomes, multiplayer). Let me focus on ONE core mechanic first:

**Which Minecraft experience should I build first?**

This is an ambitious game with many systems! Let's start with ONE core mechanic we can expand later:

1. **Block Building & Breaking** - Place and break colored blocks on a small terrain chunk. Free creative building. No enemies, no crafting, no survival.

2. **First-Person Exploration** - Walk and fly around a small procedurally generated landscape with 2-3 block types (grass, dirt, stone). No building, no combat.

3. **Mining & Inventory** - Mine different block types (dirt, stone, ores) and see them in your inventory. Small cave area. No crafting, no enemies.

4. **Survival Mode** - Health bar, simple enemies (1 type), basic weapons. Small arena. No building or mining.

Which one should I start with?
