DS GAMES RECOMMENDATIONS (tactical RPG)
Radiant Historia- if you want great gameplay with time travel + PERFECT PLOT and PLOT TWISTS this is the game! Amongst my recommendations, the art is the least refined, but it has a classical charm to it. The story is unpredictable and Stocke is a joy to play as. You don't get a lot of intelligent, stoic and focussed MCs like him.
Suikoden Tierkries- Great storyline, likeable characters, great art. 70+ playable characters. And the MUSIC IS AMAZING!!! What I like about it is the humour and the funnily blunt MC, plus the anime cutscenes. You could totally tell how much effort the developers put into making it.
Luminous Arc 2- Interesting plot, lots of humour, stunning designs (+ fanservice). There is subtle romance in it, and the soundtracks are amazing too!! What drew me in is the characters, and the voice acting.
Pokemon Explorers of the Sky: The story is AMAZING and it's so cute ^^ i mean, imagine being a pokemon and interacting with them!! Also I nearly cried at the ending.
I love these four games so much.
