Anime themed Turn Based Strategy/Tactics game set to a WWII setting features great voice acting and fun but not overly complicated combat.

Strategic music based game that satisfies your ears when you manage to make the light flow through all of the audio zones. Fun casual game.

Visual novel has a great artstyle, animation, and a reasonably interesting main character. There are tons of geeky references like Hatsune Miku / Touhou

Hard as iron space roguelike that has ship to ship combat involving lots of micromanagement. Highly replayable and involves a lot of strategic thinking.
