Continuing Fate/Extra which was in my PSP games backlog(ugh i have too much) where i left at 4th week in-game months ago. Over one week i am marathoning the game from my last save which i used Caster after clearing the game once with Archer. Unfortunately fighting through the Holy Grail War with our lovely Magical Fox Girl is really hard as expected and seriously i don't recommend playing as Caster in your first playthrough because you will find yourself Ragequit all the time.
However Caster's is definitely the more interesting route out of the 3 playable servant in which she is one of the more flirty and playful character in Fate/Extra. In Male Protagonist playthrough, there are plenty of innuendos with the interaction of Caster with main character and Caster seems more than eager to spend some "tender moment" with her beloved master. Her story gets more interesting near the end of the game which is around week 6 if you pull things right because her route is something in game which is closest to Dating Sim. Nevertheless i would recommend to go through Caster's route at least when you play Fate/Extra though using her in the first playthrough is still not recommended. This is because you will have hard time to survive in the dungeon against less predictable opponents as caster has different playstyle compared to Saber or Archer and needs more careful planning in the battle. But Caster gets more powerful later in the game especially after she gets Merciful Sky and her passive skill which makes the dungeon more bearable and make the boss fight quite a breeze. In the end Caster's route is basically Hard mode of Fate/Extra with more rewarding experience(if you don't do it in the first playthrough).
