[4]: Daemon x Machina:
While I wasn’t particularly impressed by the game at first, its positive points start to show once you unlock more parts to equip your mech arsenal with. Upon reaching C Rank the mission designs become more demanding and interesting as well, though I found by B Rank my mech was so powerful that the rest of the game became trivially easy anyway. But the final boss was brilliant - you have to know what you’re doing to stand a chance against it.
