I wish for FE to have more than one race of creatures that you can play.
I wish that it will have some great spells and effects that everyone, including the AI will use.
I wish for a world that truly looks like it went through a world ending event. (play with the x,y,z axis. add in some giant cracks, mountains, destroyed forest and strange climates.)
I wish that FE will be 100 percent working and stable at release.
I wish that tactical battles will be fun and done well enough that you could create a separate game around the tactical battles.
I wish last of all that they would have just used MOM ideas and modernized them (not fix or change just better graphics)
That is all for now. Some things that I wished for with WoM has been implemented as far as I know concerning food and housing. Like getting rid of placing houses all together and making food a global resource.
Anyway good luck and keep up the hard work
