Sadly a nostalgic version of 1999 would need vast amounts of players.
No experience is the same without regular trains to the zone in any zone worth mentioning!
My own version of events went something like this:
Neriak forest to about level 10
West commonlands hunting willowisps for the invaluable light stones
Then on to Northern Ro to hunt at bandit camps, followed by a run to high pass hold.
From there it was on to karana, and then to South karana for some massively overcamped aviaks.
Lake rathe followed, with some infrequent visits to kill Giants and cyclops.
It blurs at that point, but gun started to become a thing around the 40s, and then on to sol b for the last stretch to 50.
