Are some of my favourite games. Phoenix Wright 3 is my overall favourite, but all three games link together so you sort of need to get all of them... Plus the professor Layton and Phoenix Wright crossover game looks to be one of the top titles on 3DS early on.
For Dragon Quest, DQ9 will easily give the most gameplay; but Dragon Quest 5 is perhaps the most rewarding 40 hours you'll get in a DS RPG (or maybe any RPG)... The story starts off with the main character as a child, and it follows him through his life; there are different wives that can be chosen, and as a result a large amount of replay value (as the dialogue is vastly different depending on who you take); plus it has an optional commentary feature which has party members comment on every event, every person talked to, and every location entered (essentially press Select, and the character will speak to the party members).
Also the version of Pokemon on DS is actually an RPG too (Pokemon Platinum) with a surprising amount of content; it doesn't have a story that is as strong as other games, but it is very fitting.
I describe myself as a little dose of toxic masculinity.
