Personally I think it's the variety of characters you can use

Im for characters as well. If you don't have good characters then its like advanced wars but you only get one or two of that specific unit.
Shining force never had a weapon triangle, did it?
- large variety of classes
- each class must have unique skills that do things no other class can do and this ties into how deep the combat system is because a shallow combat system means the skills of classes will be shallow too and just revolve around dealing bigger numbers of damage
- combat system must have multiple gameplay elements you can affect and play around with, if you so choose, beyond just hp, mp, and damage
- campaign storyline must not be kiddy shit
- different types of characters, some simple, some complex, some simple on the surface, but revealed to be complex underneath
- story encounters must be challenging with a few easy encounters for a breather here and there
- a region or world map with multiple numerous locations
- plenty of secrets that are hard or fun to figure out
- meaningful post-story content
- good music
- sprite and map design must look good and visually readable at a glance
If you can nail all these, you're good
and no, if you cannot skip a single one of these requirements
