Fall From Heaven (FFH)
hehe
you can code both in (though it'd require really good coding abilities), but without graphics (which maybe can be done with quest ~ not my field at all, laughs), no one would really enjoy the game if everything is just displayed Attributes... that'd be a really messy and ugly game...
if you do 'codecademy' site, within ~halfway into the python section, they get into making a 'grid~ the battleship game', so you can make a 'tile~grid world with coding~quest... but you really need the graphics to make the game playable for people... as a 'simcity' type of game much more advanced than the simple old ("you sunk my battleship") battleship game. People don't like data~Attributes (computers do), we like seeing and touching (clicking on) graphics~GUI, and etc.
