Tbh, I'd say its worth actually paying for if you have the money, you pay for it once and the game is continually upgraded lol
Thing's that that been added since I bought
- 'The End' dimension
- Ender Dragon boss (in The End)
- Strongholds
- Abandoned mineshafts
- Jungle biomes
- Enderman enemies
- Item Enchanting
- Potion crafting
- Ocelot cats (and the ability to tame them)
- Villages
- Villagers/Testificates
- Iron Golems (to protect the villagers)
- Zombie seiges on villages
- Animal/villager cubs and children
The main point of focus of the developers at the moment seems to be the villagers
(Iron golem with villager children)
