Trust me - your sixth-form English is better than my thirty-year-stale college French :-). As tilt said - precise English is not necessary. Is the English saying also found in French: a picture is worth a thousand words? Tell us what your game needs, and what styles of maps you like, and we can help steer you to the resources to get started. What software do you have access to?

If it is not obvious - the WIP thread Tilt refers to would be a Work In Progress - you'll see such scattered throughout the Mapmaking Discussion & Philosophy forums. Post whatever you desire help with, even from an early stage, and the experts' advice can quickly guide your efforts.

Welcome!
