Wacky, Wild, Biopunk, futuristic, and mecha. Definitely similar.
report Recommended by AnimusNathan
Both series have similar aesthetics courtesy of character designs by Kenichi Yoshida. And either series is mecha with elements of biopunk - particularly in Xam'd, which isn't tagged as mecha. The key difference lies in the tone/mood. Overman King Gainer is upbeat and fast-paced, while Xam'd: Lost Memories takes a more somber approach. In either case, the setting and details take a while to be fully fleshed out.
