Released for the Nintendo DS in 2008, Sigma Harmonics is a role-playing game developed by Square Enix.

It landed about 4 years into the DS's life. Other notable DS releases from 2008 include Pokémon Platinum, Professor Layton and the Curious Village and Sonic Chronicles: The Dark Brotherhood.

Square Enix also made The World Ends with You, Final Fantasy Crystal Chronicles: Ring of Fates and Final Fantasy Tactics A2: Grimoire of the Rift for the DS.

This is a solo experience: one player, no waiting on anyone else.

Pick it if…

  • you want to get lost in a long quest
  • you have time for an epic journey (20+ hours of adventure)

Maybe skip it if…

  • you want instant action rather than menus, story and grinding
  • you are looking for something to play with friends
  • you only have a few minutes at a time

What playing Sigma Harmonics is like

Role-playing games trade reflexes for strategy and story. You build a party, level up, manage equipment and travel across a large world, usually through menu-based battles.

Tip for newcomers: Retro RPGs can require some level grinding and rarely tell you exactly where to go next. Talk to every townsperson, save often and use a guide if you get stuck: there is no shame in it.
