They are adding mecha, that is half the battle right there but here are a few extra suggestions.
- Keep the large beautiful and various landscapes for the player to explore like Xenoblade.
- Remember to have memorable characters, the cast doesn't have to be massive, just give them enough story and personality to shine.
- Have it released no later then December of 2014. Strike while the irons hot and the Wii U could use it as a system mover.
