my mages cast crap spells?

[Sombre]

Yes in terms of multiplayer it's rather more complex because different people will have 'banned' or 'greyed out' different spells. The game would have to keep track of all of them, although it isn't like that would be any more complicated than anything the game currently keeps track of.

This isn't the sort of feature that can just be stuck into the game, unlike new units and spells and alterations to message text. On the other hand, it can't actually be /that/ complicated can it? I mean to the people who made the game from scratch. It's not like we're asking for a major altertion to the GUI or to the way the game works.

Currently the game checks your research level against the level of the spell and says yes you can cast it or no you can't (ignoring other costs for the moment). All spells are simply given a required level, there's no 'I've been researched' flag. But you can restrict spells to nations and via modding (every turn) you can do it on the fly, provided the mod is loaded from the start. That means it's currently entirely possible to alter a spell so it's no longer available to cast (by resticting it to a non existing nation). The complication here is that different people will want different restricted lists and the AI will want nothing restricted at all. But again, that doesn't seem like something too hard for the coder(s) who made Dom3.
