Question Questions on zone completeness/balance in tbaMUD 2020

A couple questions related zone completeness that I really haven't found any docs for.  I DO NOT want to get rid of the stock Midgaard zone.

1) Are all of the zones in the 2020 download pretty much tested and ready to go?  If so, are they "balanced" a bit for the 4 stock classes that it comes with?
2) What is easiest way to find the entry room into each of the zones?  Is it generally the first room in a zone file?  I know I can use my imm to run around, etc. but I was hoping for a "quicker" way to see what they are like to not only possibly use/modify, but also learn.
3) Is there a list of the zones/levels somewhere to be found?  Or will I need to open every zone's mob, item files and figure stuff out?  The zone "secrets" would be helpful too if possible (keys, portals, secret words for mobs, etc.).

With those questions asked, I DO plan on adding/removing/modifying zones before I publish my Mud.  I'm just worried that I won't know how to "solve" the zones that I do end up using (which I hope are a lot of them).

Thanks all!

1 The zones in the download are _done_. I would not expect them to be balanced.
2 Almost all of the new zones have a "description room" at the first number. So "go 10600" will show you this: 3 A lot of the zones have detailed descriptions, but you'll probably want to at least skim the files before connecting them.

Remember, as an immortal (and especially as an Imp), you have access to "stat room", "tstat" and similar commands, letting you quickly check any keywords, etc.

Thanks so much for the info. I will try using those functions and see how it goes. There are SO many files my head is spinning lol.
