Hi,

What sort of graphics adventure? A text adventure
with graphics, 'The Pawn', or an interactive one,
Zelda/Final Fantasy?

For either I'd favour C for most of the game logic as
you'll be doing lots of array lookups and cross lookups,
mulitple arrays , string handling etc. These are a pain 
to manage in assembler. Also, nothing is really time 
critical here but I note your concerns over space.

I'd also go for using asm routines for displaying graphics, 
but mainly for the efficiency gained.

Regards,

Mark

P.S. Also using more C means it easier for converting to
other platforms ;-)
