It's been a while since I've last played zone, but from what I know and remember here's what I think needs to be done: (feel free to correct me if any of these have been fixed, but this is my opinion, remember that)
• better F2P model- think of some things that you can do and present them to Stefan, all server managers, pic and mobile alike, should honestly be thinking more of how to make the IAPs more appealing without detracting from gameplay. Almost every manager has failed to do this so far, so if you can pull it off you'll be accomplishing a lot more than just increasing your player count
• add some rewards for exploration and expand the world. The game takes place in the future, and space travel is all about exploring new places and finding cool weird things. This is exclusive for iZone too, so make sure you really focus on building an all-star levels team who loves making new maps, cause the server needs a lot of em.
• make some other servers' eras an inspiration for the items. Make stuff that looks like it began as an M4 for example, but evolved over several centuries of technological development. And when you do this, don't make them better than the already futuristic guns, please.
(I typed these up on my PC so I cant add the bullets)
- Make the quests mean something. Have events involving the planets' relations, for example a war between skyworld and maybe the magma world begins, so any quests you do on the planet for its government (like taking out baddies and such) increases your affinity for that faction, contributing to the war. The winner of the war could get a limited time shop with items themed for that world
More to come, stay tuned
