Summary: This must be one of the best DS games out there. And no random encounters! I'd recommend this for anybody looking for a good jRPG with an engaging story and many hours of playtime. It's also non-linear so feel free to explore and do side quests. I do prefer games with more interaction between characters. By design Sentinels of the Starry Skies isn't one for character development, but I'm sure you can still enjoy it.
Summary: This game is my favorite game of all time, and I'm a big gamer. I've sank well over 200 hours into it. The story will take you around 100 hours. You have to grind a lot, but it's so much fun. And the post-story quests will easily take even the best gamers at minimum another 1 or 2 hundred more hours to beat.
Summary: This is a must have RPG for the DS (or your 3DS) but your mileage will depend on your tastes. If you were bred on old school NES RPGs like Final Fantasy or Dragon Warrior I/II/III, then you will definitely love this game. The battle system combines the tension mechanic from Dragon Quest 8, with the job system from previous games (III, VI, VII).
Summary: I adore this cutesy game. You have the power to fully customize your character up to the clothing, job/class, and skills and spells you could learn. I've contributed 200+ hours upon this monster and still have a ways to go. You can harvest, kill monsters, and play with the Krock Pot. I recommend this game for those who like turn-based games and animated cut scenes. The Amazon services were also pretty good, considering it had to go to Alaska. Thanks!
Summary: This is the first game I've played from the Dragon Quest series and I am in love. I can't believe I hadn't heard about this sooner! The combat is typical of a handheld JRPG- walk around, approach enemies, combat screen appears, fight them with your party. Win. Yay. But it's so much more than that. The game is reasonably difficult, and requires the grinding I have become so fond of from JRPGs. I even find myself following along with the plot! Imagine that.
