Town Levels?

I've had a sudden crisis of confidence regarding my town level. It will probably be the last thing finished, but I find myself asking: do I really need it? Its very incomplete at the moment - no NPCs or plot-related items.

Here are some alternatives:

• Get rid of town levels entirely and adopt the Crawl approach.
• Get rid of town levels as such and allow their functionality to be inherent (for example the character has a device that can teleport him/her to an "extraplanar shop" at regular intervals)
  
• Implement regular "outpost" levels (that would be safe) that function as mini-towns.
  
• Implement an overworld (or rather oververse) map (almost like the old version of Kharne)
  

At this point I'm not sure what I want. Analysis paralysis ahoy.

Bah, I hate having existential crises!

NLarn

One of the legendary roguelikes (and thus one that I'm also not very good at) is Larn. Its currently being remade and looks absolutely gorgeous:


It almost makes me regret not having an overland map. If I had continued with development of the original Kharne, then I would have had an overland map. I managed to dig this out of an archived folder which hadn't been touched for eight years or so:


This would have been the overland map for a future release of Kharne the Revelation.
