Recommend Me Some Short Games Played on PS2, PSX, NDS, or PSP

I'll be playing on my phone so the controls are a bit hard so action games are out of the question.

I was thinking along the lines of Turn-Based RPGs like Persona 4 but these are too long to play, I just want something short.

Here's a short list of Games I've liked so far:

1. Suikoden Series
2. Final Fantasy VII, Crisis Core, and Tactics
3. Persona 3 and 4
4. Bully

Upon reflection, maybe something similar to JRPGs but without the grind.
