i think we may see player spell casting.. could see catapults and ballistas
and stuff like that eventually as well.. maybe gunpowder, who knows.. we've only seen about 20% of what they consider final product, if their version numbering means anything.. so this is just the tutorial part that introduces the basic game mechanics.. sort of like leveling a WoW toon to level 20 back when 100 was cap.. but in this game advancement means technology, so i assume they are aiming for higher tech, which means machines and probably magic because why not.. it's obviously pretty doable with the engine..
