Ok so we have the following items for Gua thus far.
- Website (check)
- Block Explorer(check)
- Faucet(check)
- Fun Games for Guarany (not-check)

so on the last "fun games" item.
we are in progress of launching a new GuaCraft server (Guarany MineCraft)

and like your opinion on this, yes its been done for bitcoin we know.
i'm also looking for in-game mods that we could add to spice up a few thing so pm me if you have ideas.
