Vaipen:
Let me ask you, what is the best thing about magic in a game.
My personal opinion:
1. Fun
2. Differs from reality
3. Fun
4. Visual effects are nice
5. Requires a bit of thinking and knowledge about effects, resistances, effectivity
6. Fun, did I mention it already?
7. Is the path back to my inner child (creativity, imagination, fantasy) - a harmless way to feel allmighty and doesn't interfere with RL ( revival of "magic thinking", development in child psychology)
That is, if magic is defined as neglecting science, reality and nature laws.
