With that in mind, our first planned change is to convert every existing PLEX into 500 PLEX. After the change, anything you could get for 1 Plex from CCP will instead require 500 Plex.
This new PLEX granularity will allow us to sell smaller PLEX packages, and allow you to trade whatever amounts you like with each other.

Q: Will market histories reflect the change in PLEX value?
A: New PLEX will be a new item type, getting its own graphs and history data starting from day one and leaving old PLEX data unaffected.

Q: With smaller PLEX, will I be able to buy less than 30 days of Omega time?
A: We currently we have no plans regarding smaller game time packages.
I want to make all the eve jsper aware so there is less confusion.
