I notice when i go underground, there are groups of gold, copper, and coal (or platinum) can be discovered. I was wondering if maybe it can be used for something!
My suggestion is to add a mining mode. Players play either free-for-all or teams to go underground and find those metals. When those blocks were destroyed, it'll earn you money. For example, destroying a copper block will earn you $5, coal will earn you $1, and gold will earn you $10. What you have to do is to reach to the bank so that way, your money will be safe. The reason you should have the bank is because, if you run into lava, you will lose all your money. I'm not sure if the same could be done for water, but you'll do the deciding.
I find it funny that people don't want this game to be anything like Infiniminer when it started as an Infiniminer clone and is still very similar (and to a degree still not as good). But that's neither here nor there.
I'd love a mode like this, honestly. Something where teams have to build a base and designate a dropoff point for minerals, then dig underground to find minerals and return them to the base, using the funds and minerals for some nefarious purpose.
