i would absolutely love to see more fire emblem characters at voidtreckerexpress! from what i see it really fits what you're looking for: it's small-medium sized and the pace is about the same. the game's setting is a train that travels through various dimensions, so there's a good mix of slice of life moments (when the train is traveling) and more action/exploration elements (when the train stops and the characters end up in a different world with a mission).

from my account it's probably obvious that i'd love to see emmeryn (especially since i play inigo as lucina's sibling), but mae or linde would be great too!
