1. lootable ships
2. lootable avatars
3. lootable fueltanks
4. 10% pvp ammo cost for everyone like in fort events
5. special pvp skill that only increase in space pvp and contributes towards reducing ammo cost further by up to 90%
6. ammo spent in space pvp goes in cargo mission pool
7. every space server has one 'control station' which can be claimed landgrab style. Controlling that station gives revenue from hunted spacemobs on that server as well as income from a part of the decay of each warp drive passing the warp gates on that server.
8. npc robot faction with fleets consisting of motherships, battleships, destroyers, bombers, interceptors, dropships is roaming the universe and attacking players as well as control stations
9. control stations in robot hands make warps over these gate points more expensive
10. control stations in own hands make warps over these gate points less expensive
11. robotships can loot players and carry playerloot as additional cargo visible with a flag
12. players can loot robotships and regain playerloot from robotships
13. warp is no longer instant but instead fast travel and the higher the level of the warpdrive the faster the traveling speed
14. shields/torpedos/different gun turret types/ cloaking devices/ radar
15. robot ships capable of utilizing radar just like players to track down and follow players as well as calling in closeby robotships to their assistance
16. jammers to block communication for robotships
17. tractorbeams/salvaging of shipwrecks
18. drones/asteroid mining
19. wave events in space
20. hunting of space mobs spawns stronger/more spacemobs in the area
21. decoys to drop aggro of space mobs
22. aggro of spacemobs is not avatar related but shiprelated and mobs will keep attacking the ship even with no avatars 'outside'
23. different levels of decoys can be used to aggro spacemobs from a vast surrounding to speed up collects for hunting or to prepare 'traps' for other ships
24. privateers can land planetside and motherships can enter 'high atmosphere' allowing smaller ships to fly in/out without having to pay 'entry tax'
25. entry tax and tp fees go in the cargo mission lootpool
26. crafting terminals in space / space only blueprint discoveries in lootable environment
27. lootpools for planets and space are separated and no longer 'shared'
28. repairs on spacecrafts are more efficient the closer they happen to the damaged part / more damage 'zones' for spacecrafts / more local 'repairpoints' for each section
29. so much more ideas i could write books
