If you're into base defense/base invasion games then you should give Valkyrie Entertainment's Guns Up! a shot. The game's free-to-play model is fair and there are plenty of reasons to keep coming back for more and more action-packed warfare, as long as you pace yourself.
It has its shortcomings, but Return To PoPoLoCrois is worth checking out for anyone craving an old-school RPG adventure.
While an improvement over the original release, The Witch and the Hundred Knight: Revival Edition still has its problems. The weak story and annoying characters are still front and center, though the Tower of Illusion is a nice new diversion from them. If you're a hardcore Nippon Ichi fan give it a shot, but pretty much everyone else can give it a pass.
