Zone of the Enders: The Fist of Mars is a very nice and entertaining mecha tactical RPG that may be abit too easy or tediously long but the storytelling and presentation is where it really shines despite not being too special. It is also told in a visual novel style and despite how simple the actual plot and characters are, the situations/episodes aren't stupid. It also gets really interesting as you further progress and its ending is great too. The music is nice too even though there is lack of variety. I'd definitely recommend giving this a try especially if you enjoyed Zone of the Enders/The 2nd Runner.
