If you're a fan of SRPG games (like me), then you will instantly enjoy this game.
Firsty the graphics are actually nice when you consider that they are on a DS, The introduction, while being typically Japanese is really nice.
Voices are present in this game as well, not in every scene however but they are included in the most important ones throughout the game which is fine in my books. Also the dub voices are actually not that bad in this game.
The actual gameplay mechanic is fluid with you commanding your army of people to achieve certain objectives outlined to you. There are plenty of characters to select from albiet not from the very start but once you begin progressing through the story then more characters will join you on your quest.
As with most RPG's you need a good story to carry the game along and while Luminous Arc is a little cliched, I actually found myself really liking the actual story line and as such kept playing this game until I completed it. The way the story is told through character conversations is the best the DS is really going to get but I felt Luminous Arc did a great job of explaining the story to me.
Overall if you're looking for a great RPG/SRPG game on a handheld then Luminous Arc whilst not the best on offer is certainly a very stellar game and I would easily recomend getting this game if you own the console. Plus there is a sequel already on the way which I will look forward to playing on as well!
