Tile based game as port of Nethack-style roguelike

[bx83]

I want to create a version of Nethack. How complex is tile-based games? We’re talking:
-a small map of where we’re at
-commands through a simple command window
-movement through numberpad

How possible is this?

Of course it is possible, but I recall you were already doing a tile-based game before?

Searching for "tile based" or "grid based" on forums will give multiple topics, old and newer ones. Of course grid algorithms are universal, so copying code examples from any other languages / engines might also work.
