Want to play Fire Emblem and don't have a Nintendo device?.. Get an emulator.

But aside from that, this is probably the best alternative on PC. A nice twist on the formula by having squads rather than individuals, lengthy campaign with room for customisation. Tech tree, upgrades etc. I do feel like it could have benefitted from a little more unit variety, you can see most of the available units from the get go and the story is just ok. But it's a good kid with a lot of heart.
