I'm sorry, as much as I enjoy Phoenixes, I can't justify starting all over again from scratch. Especially since the save breaking changes only benefit you and new users, while shafting your entire current user/fan/customer base. You could have at least worked out a compromise, whereby current users could start at the beginning of the new content instead of all over again from the beginning, like CoR did after large loses to their customer/fan base due to updates repeatedly breaking their saves.

While I'm more of the "welp, this happens sometimes when playing WIP games" school and will doubtless start over, I agree that the approach CoR used is a good one when possible and encourage considering it (even if using it might mean the player skips over newly inserted content, I guess)
(side note, I don't agree that a save breaking change necessarily only benefits the devs and new users, if the result is a better game then all the players benefit in the long run, which I guess is why I'm philosophical about it)
I've never played this game before, it's currently downloading to my PC. However, as a fan of other games, it's always nice to take some time and revisit the early content of my old favorites. Specially if it gets improved like it did in this case.
Why not give it a chance and see what has improved? You might actually enjoy it.
