• Water & Lava Physics: Fluids spread infinitely but slower. Finite fluid control is a key challenge here.
• The Nether: Added in Alpha 1.2.0, still present in 1.2.6. Includes: Netherrack, Soul Sand, Glowstone, Ghasts, Zombie Pigmen.
• Biomes: Very basic biome system (first introduced in Alpha 1.2.0). Includes: Forest, Desert, Tundra, Taiga, Swamp, Rainforest, Shrubland, Seasonal Forest.
• Lighting: Smooth lighting does not exist (added in Beta). Darkness is very stark; torches are essential.
• Leaves: Do not decay when wood is removed unless you manually place them.
• Sponges: Do not work (they are purely decorative, water-absorbing function came much later).

Today, a dedicated subculture of "Alpha players" refuses to move past this version. They aren't just being nostalgic; they’re looking for a specific type of gameplay. Without the "feature bloat" of modern versions—no enchantments, no hunger bar, no sprinting—the game becomes a pure survival horror/architecture hybrid. minecraft 1.2.6 alpha
