I have two ED:O accounts...
However, up to this point there's really nothing in Odyssey that appeals to me enough to put up with bugs, terrible UI, and lack of VR support.
Luck for me, both my ED:O commanders are sitting on a billion cr. each.
Once the split happens, I plan to play exclusively in legacy mode unless FDev actually rebalances engineering or VASTLY improves some other ED:O content.
For brand new players, there's really no reason to play legacy unless you can't run ED:O...
If this game has a future, that's were it lies, but I'm skeptical.
