Minecraft has became something like this:
1. Get wood, make wooden tools.
2. Get stone, make stone tools.
3. Get a shelter, get coal and make torches.
4. Get iron, make iron tools.
5. Get diamond, start over.
Seriously, I can't wait for the adventure update to come out, I hope it brings up my interest to Minecraft again.
This is how you make the game sell millions and players get bored after a while:
1. Create a random generator.
2. Add some random monsters and item-making abilities.
3. Profit.
In my opinion, Minecraft needs more stuff, not just those stupid dungeons which you can clear in 10 seconds.
There needs to be a wider variety of weapons and kinds of monsters. 8 monsters aren't enough.
