Sure, you (singular or plural) are free to do so any way. Below is my suggestion, which you are free to ignore:
1/2 Decide on big scale things
Let all members suggest the thing they want on the road map. Suggestions are: (1) complete menu structure, (2) an options screen, (3) a minimap, (4) a minimally playable game, with element such as (a) dying, (b) targeting system, etc.
Vote on each item to be the most important. That will be first item on our Road Map
Vote which item is most important. This will be the second item on our Road Map
Do this for all items
2/2
On the most important thing, create Issues. All other Issues should/can be labeled 'Low' priority.
From the last evaluation it was suggested to create a Road Map. Do so.
