Well the first thing you need to realise is that you are not in any way limited by the World Editor.
The most important step is determining the
style of the map.
Note that these are VERY general and i may miss them.
You have;
- Dota Styled (hero combat)
- Footmen Styled (unit combat)
- Tower Defence (waves of creeps to be thwarted by buildings)
- Hero Siege (waves of creeps to be defeated by heros)
- Role Playing (combat adventuring questing etc)
- Survival Styled (get a unit to survive against certain adversaries)
- Hero vs Hero styled (think angel arena)
- Mini Game styled (think Uthers party, Sheep tag other misc. games)
These are how 'I' classify maps, others may have different ideas, but i believe i have covered the types of maps.
So You want your Map unique? (so does everyone) but you have to identify an
OBJECTIVE. That is, the purpose of your map.
Will it be team based?, FFA?, Co-op vs creep?
What is the level of 'power' involved? none low medium or high? [to determine this compare sheep tag (none) to dota (medium to high) to angel arena (ridiculously high)]
Who is the Characters 'protagonist'? Hero, builder, army etc
If you work that out you begin to develop your game from 'where do i start, what should i do' to 'right, now what'..... (thats the hardest part)
I have a suggestion but i will post later
