Yay! A word to the modders !
Planning to start modding after 1.0 hits for the same reason you stated- stability.
A few things I noticed that bugged me:
Testing wizard- a way for modders to check if their stuff works. It might be possible with custom maps, but letting the modder test it "properly" while in-game, without having to reload the game every time will be lovely.
Tags being "unknown". While I could go to the list of already-made spells and look for the gimmick I wish to introduce, I have to remember the name of the spell or the game term in order to find it.
Tags missing- While there is a tag to pull the player's amount of mana, I couldn't find a way to pull the amount of gilder (for example) he has. There should be tags for everything in the game (such as Get_CasNumResGILDER or Get_P12NumUntTotal(power>500)) or however you decide.
Hardcoded things- puts obstacles in the way of modders. An example of something I'd like to imitate is the cloak of fear, that rolls a magical attempt to know if it works. I'd really like to know how to make my own spells initiate such effects, but it's both "hidden" in the code, and knowing it's there wastes time by attempting to find it.
Assuming it's not hard, resolving the workarounds some modders have to employ. For example, I saw a thread on the forums with a modder requesting guidance on how to create a new shard. The workaround was quite long. Besides causing the modder to work harder to insert something into the game, it also causes additional stress (if the game has to remember an additional value into account and calculate it all the time... I'd usually call it bad programming, if it could be avoided).
I am not sure if this is possible at this time or not, but allow modding for the terraforming, in a similar way of the settle; outposts and roads. Giving a modder the ability to build, for example, 3 different outposts with different abilities instead of the current way. Thus also changing certain properties such as minimum range to build from city, itself, or the effects of the terrain on it.
Thanks a lot for giving us this game. Keep up the good work!
