You should buy the boxed version if you intend to purchase those five model packs because you should be offered a substantial discount at checkout. Also, the normal version makes it possible to use FPSC mods such as Ply's Mod (which you will want if you're planning a medieval/magic game). Lastly, the boxed version comes with a bunch of media which is not included in the Free+upgrade version.

Yes! However, the magic may or may not end in failure because I'm trying to find a workaround for sound effect playback issues. Be advised you will need Ply's Mod to get the foundation for a
good magic system.
