i've read a few concerns about the use of the Teleport spell, and how it can be abused or too overpowered... my idea would be to implement a mod that removes this as a spellbook entry, and instead provides a researchable option for a new building type - the Kingdom Transport Service (or something more aptly named).
the rough idea is to have the player research for this building type, and once available, it will allow any unit (or units?) to transport from City A to City B... requirements would be:
- city level
- research the building type
- having the building type available in both locations
- associated cost per transport (materials, or crystals, or...)
before i dive headfirst into the XML, does this seam like a feasible scenario? is this even possible given our current knowledge of the games mechanics?
