The best thing in FE??

That is one tough question becasue I love/like so many things in this game.

If there can only be one I guess it is city development. I love how I can make my cities snuggling with the vast forstes I preserve and placing each building in an RP context (workshop near the iron mine, cleric tower at the life shard that will become the true heart of the city, belltower not to close to the horses to let them find their peace). I even find myself switching dozens of times between two buildings just to make sure that the one I intend to place faces the right direction and even though it is anoying that this is random it is imo always worth the time.

The best part on FE is graphics. Seriously, that's how I see it. The rest is just flawed in one way or another - not necessarily bad, but surely flawed.
