I can't give you really obscure titles since I barely played DS games when it was new, start at Rune Factory 1 and play through the series in order, it's worth it.
It's exactly what the title says it is, it's Harvest Moon with comquat and crafting that tie into each other. You go around and talk to characters in between the other aspects to get dialogue and backstory. If you liked that in Mass Effect you'll probably like this.
There's also monsters that you can tame and have fight with you against other monsters. Each monster having their own various attacks and health.
It's a charming series.
Also try Trauma Center, there's two games for the DS.
