JRPG lover? You want ACTION-Based RPG and not turn-based? Want the pixels? Love to grind? Don't care about the story? Want to customize your charater's appearance from top to bottom? Even if the story is lackluster and if you're in doubt if this game works, just give the demo a shot.
A brief warning. This game is a PSP port and its' multiplayer features is not implemented fully at the moment because the PSP port's multiplayer works in ad-hoc mode (via playing locally). However, if you want a good JRPG game while your internet is screwed over, pick this game up immediately. People outside the JRPG realm?... Hard to say. There is a tutorial on it, but this game will not hold your hand once you get out of Trial Island which is more than enough for me.
This game can easily fill in 20-40~ hours of gameplay AT THE LEAST. It can go more when you want to reach cap on 8~10 different characters (Level 99 is the cap)
Oh, and not to forget to mention there's a Job Changer, so you can do the same grind, AGAIN! And max initial cap of any stat is 999. The universal cap is 9999. So I still got a lon♥♥♥♥♥♥♥♥♥♥ way to go.
The learning curve is steep when the "Magic Circle" system is into play. Basically, you can stack your sub-characters together with your main character (the one you physically play with), and the stats get transferred to your Main Character while special tiles like "Growth" will determine your Sub Character's Leveling Parameters.
If this looks like rocket science to you, this may not be the game to pass up and if you want a simpler game, I will forward you to Binding of Isaac or Hack, Slash and Loot. Heck, even Desktop Dungeon (its free, and not on Steam). For a roguelike with a slightly higher learning curve, I recommend Dungeons of Dreadmor.
In addition, I have a 4 1/2 hour stream of a first game impression by me if you want to check that out: http://www.twitch.tv/critical__hit/b/328931483
