Since it would be easier to get together to play a game on laptops than transfer saves/data/schematics for something like armored core, would any mecha fans like to get together and play something like Exteel?
Exteel is a free multiplayer game where you customize mecha(they tend to look like gundam ripoffs) and just have at it in a small arena.
Also a fun mode where you need to hold off hordes of spawning enemy mechs with a team of player characters.
Flawed? Yes.
