RPG's I've played before:
Darkest Dungeon
Fossil Fighters
Pokemon
Earthbound
Final Fantasy

Things I like in turn based RPG games:
-Power spikes, in which the player acquires some ability or item and becomes significantly more powerful, being able to go through areas they struggled and win effectively.
-Strategic thinking is rewarding and achievable by the information given to the player. (You don't go into a battle with the wrong characters to learn the strengths and weaknesses of an enemy and get instantly destroyed with no chance for an escape as punishment for having the wrong characters.)
-The grinding is not ridiculous. (I.E. Each level only gives +1 to each stat which have high base values, and to level up your required to gain around twice as much experience as the last level required of you.)
-Proper solutions to players that get too high in level for an area, whether it is on purpose or accident.
-Style, in which Earthbound and Darkest Dungeon are very good examples of this for me, I'm very open minded to what kind of style it is as long as it is done well. (With the exclusion of surrealistic sci-fi, but if it's goofy sci-fi like Psycho-nauts I'm totally okay with it.)

I understand that not all of this can be found, especially considering how specific and needy my request is. I'm okay with taking the second best option.
