Doraemon: Nobita and the Steel Troops
What they share
Both films are directed by Tsutomu Shibayama, and they both carry the playful mood tag, and they sit in Adventure / Animation / Family / Fantasy / Science Fiction territory. If that's the register that drew you to Doraemon: Nobita and the Knights on Dinosaurs, the second film will land in a comparable space — through a different lens.

What Doraemon: Nobita and the Steel Troops is
This one asks, what if kids had the tools to build their own war machines? Nobita and Doraemon construct a giant robot, unaware it's a weapon in an alien invasion plot. At least they provided the other kids with a fun summer project.
