My ideas for a Minecraft game (can't recall if I indexed this page):

• Set on a single island, but can change via an ark.
• Low poly characters rather than blocks.
• Megaman Legends ancient bots. Dropship air pirates?
• Cortex Command brain controlling bodies mechanic (rather than lives & respawn).
• Guns and satisfying pressure explosions.
• More persistence (enemy deaths, block editing speed, destruction states)
• More elaborate treasure hunting mechanics, and dungeons
