There aren't very many games for PC which have gameplay like Ogre Tactics, Disgaea, and Final Fantasy Tactics but I've been looking for them. Yet even on consoles where there are more strategy RPG's, there are not very many which were given E or E-10+. Therefore I turn to you, the knowledgeable RR community.

1) What are some tactical RPG's for PC which have gameplay and isometric perspectives like these games? (i.e. square-grid-based, height-dependent for attacks, which direction you are facing for defense, turn-based games where you level up your characters, upgrade their items, and learn skills to progress through a single-player story)

2) What are some comedic games of this genre?

3) What are some games of this genre that are E or E-10+?

4) What is the difference between tactical and strategic RPG's? Are there further difference in these definitions between PC and consoles?

Thank you for any help!
