What does the 47 stand for?

How about SimCity 84?

Also change it in the topic title

Looking nice!

expect free bugs

There are paid ones?

Just kidding, this looks quite good. One suggestion I have, though, to stand out from the competition, would be to maybe use dual-layer ASCII tilemaps (drawing two sets of characters on top of each others) so you can use sprites, but without losing too much speed, kinda like Serenity, Zoith and Metroid Pi.

There isn't, but someone made a program that can help you create dual-layer ASCII sprites:

By the way, here's how a game could look like using them:



Basically, it rivals some xLIB/Celtic III graphics. I don't remember where I put the code for this, though (it could have been handy for chars combinations).

Try to get the main engine done first, though, to ensure you got full speed and optimized everything before adding eye candies that could slow things down.
