Valkyria chronicles 4 at the moment.
I downloaded the first Valkyria Chronicles long ago, but finally played through the entire game during the start of the year and enjoyed it immensely. The game certainly was unique with the whole 3rd person turned based time strategy mechanic. Adding in some memorable characters, good music, customization for your unit, and a new game plus mode has launched it into my favorite game list ever.
So now I'm playing the 4th installment. It hasn't reached the levels of the 1st game nor has the charm, but it seems to be picking up speed the further I progress. Hopefully the next few chapters will have me hooked once again.
