Just an idea. I know that iZone is still developing, and I'm sure they're making more planets, but I just want to say my idea for moneymaking.

Unknown Planets-
Players can use spaceships and go around space. Players can find the planets, land on them, and explore! The map won't be complete until the player has fully explored. Players can kill aliens, monsters, and also mine rocks to get certain items. Aliens and monsters can drop their body parts and certain minerals for the player to sell. They could also drop weapons at a low chance for the player to take. Players can also revisit them once they have found and explored the whole place, but if they leave without exploring it all the way, they have to look for it again. It could also unlock certain missions that will take place in the planet.

Meteorites and Junk- When you're on the spaceship or at a planet, you can find stuff like meteorites, stars, small moons, that can be sold. As for junk, players can find them on unknown planets. Almost like trash on era, but they can also be used as furniture. When you find one, it'll be placed in your furniture selection, and can be sold there.

Material Collecting Mission- Let's say there's a new player, new to graal and all, and doesn't really know how to shoot accurately. The player wants to make money, but keeps dying in missions with enemies. This mission should be about finding certain things and bringing it back. No enemies or something, but there would be moving targets. Like a tutorial planet. Whenever a moving target is destroyed, the target might drop a material for the player to sell. The player gets materials to be sold, and gets money for finishing the mission. It takes a long time to collect stuff, but would be good for new players. Finishing the mission wouldn't give a bunch, but enough to at least get the player a new robot when finished a couple times.

These are all I could think of, lol. I'd say the most important one is material collecting for new players.
