I know very little of modding in general, but I thought it might be a cool idea to have a mod based on Fire Emblem, say the continent of Elibe, from <I>Sword of Seals</I> and <I>Blazing Blade</I>. You could have Bern, Lycia, Illia, Etruria, Sacae, Nabata, etc. as factions, and heroes like Eliwood, Roy, Hector, Lilina, Lyn, Zephiel, Nergal, Brendan, Sonia, etc. and maybe special recruitable heroes like Nino and Jaffar. I have no idea how magic attacks, or wyvern/pegasus riders could be integrated, or the dragons themselves, but this is just an idea. After seeing what's been done with <I>Hyrule: Total War</I>, I thought it might be something worth looking into.
