Why not.
You can use it as a learning curve.
Try to implement every new or improved idea that comes to mind.
You won't know if the players like it until you try.
Interlude is not meant to be customized in the first place.
I will never open an Interlude client again (I bet many others think so), the way it moves is mediocre compared to the new chronicles.
Interlude vs. New Chronicles is the same as Windows XP vs. Windows 7 and later. Eventually you will let it die. Sooner is better.
Take this advice from someone who have played this game since 2006 and developed it for the first time in 2008/9: Try new chronicles and work on them. Interlude is a BIG waste of time.
I could say more details, but I hate to do it on the phone. I left Lineage 2 behind in 2012 and Classic is the only reason I came back (partially) to it in 2020.
