giant robots YIPPEE!!!
Genre: Mecha, but with some clear super robot elements
Touchstones: Gurren Lagann, Super Robot Wars, Neon Genesis Evangelion (especially)
What is this game?: Steel Hearts is a game for fighting robots and aliens in a future sci-fi setting, with distinct anime flavoring
How's the gameplay?: Steel Hearts features grid tactics combat with an emphasis on reaction play and d6 pools. As you and your allies make attacks, you build up a resource called "synergy" that lets you take actions off-turn. Your mechs are built part-by-part, so you can truly call your robot your own. The combat isn't as tactically demanding as some other grid games, but there's plenty of room to come up with wild combos.
What's the setting (If any) like?: Steel Hearts takes place in the "New Century," after the emergence of alien monsters called "Wyrms" has reshaped Earth's political and ecological landscapes. By default you're teamed up with the Earth Defense Alliance, but there's a whole cast of factions jockeying for position.
What's the tone?: The book is light and upbeat, but makes no secret that people will die. There's a decent chance of whiplash when your "Bard" pilot whose mech covered in audio equipment is forced to confront the shared humanity of those it's killed, but, that can be a fruitful contrast!
Session Length: uhhhh can't tell so I'm gonna guess 2-3 hours
Number of Players: 1 GM, 3-5 other players
Malleability: The mission loop should be adaptable to a wide variety of settings, many of the mechs are associated with specific in-universe factions or events but the mechanics don't explicitly interface with them.
Resources: Automated mech builder sheet available in the Itch forum
Warnings?: This game is unfinished, and you will need to homebrew NPCs and mission biomes yourself if you want to make an extended campaign out of it
Steel Hearts makes some decisions I don't quite understand (like intentionally invoking dnd comparisons several times), but as soon as it's actually done it's going to be my go-to grid tactics super robot recommendation.
