Big question is:
Singleplayer (campaigns mostly) or Multiplayer?
SP is much easier to do (don't have to worry about multi unit instanceability (mui) and you can even get away with leaving leaks in many cases).
I am in the same league,
probably started 20 projects over the years, got some to 50%, but most maybe to 20%.
Sometimes getting frustrated with limitations:
- not adviced to have more than ~80-100 units per player, or the pathfinding gets laggy
- can only select 12 units at any time, sure there are workarounds like Mass Selector/Mass Commands (age old starcraft bunker map even had that)
- map size limit of 480x480, in sp you can access the mapcache for multiple maps (e.g. Rexxar campaign), but for mp feels pretty limiting
- if choosing a size past 256x256 (what was considered legendary before reforged) undead blight gets dysfunctional past the original 256x256 square
But, that's all pretty idealistic really - this editor is still extremely powerful and pretty easy to get used to.
And we don't suffer from that hideous 4 MB limitation anymore!
Also there are powerful systems, which have matured quite a lot, making triggering much easier and convenient even.
(damage engine, gui spell system, unit event/unit indexer - well yeah, i'm a little Bribe fan)
I came to realize, that struggling with focus is not necessarily a detriment, same goes for procrastination.
You can try to embrace it and work "chaotically" (at least how straight-shooters would describe it).
With the former, you can move your project's progress forward very carefully (and from many angles).
With the latter, introspection comes naturally at many steps, giving your subconscious time to entertain new angles.
Then there is also overthinking, so i should stop now.
Maybe you want to share more details too?!
