So back when I got a bunch of free Amazon Coins that were expiring I went and bought a bunch of games that sounded cool. One of them was
Hitman GO which I have now played a bunch of and really enjoy it. A turn based, board-gamey version of Hitman and its really quite good. A bit of replay value since there are 3 challenges to meet per level other than simply finishing. You might have to finish the level with no kills, or all kills, or grab a briefcase, or reach the end under a certain number of moves. Sometimes all 3 can be done at once, but it seems like many levels you will have to replay them to complete one or two. Usually if there is a briefcase and a turn limit they are mutually exclusive.
There was a more recent follow up with
Lara Croft GO, obviously based on the Tomb Raider series. It is currently on a holiday sale for 99 cents, so grab it while you can. Same idea with a new skin and its own twists. Levels are more linear and do not seem to have side goals like Hitman, but the puzzles can be more intricate since you have levers, moving platforms, crawling on the sides of things, and collapsing elements. Really cool game that so far has managed to capture the feeling of the old original Tomb Raider better than the modern mainline games.
EDIT: Hitman GO is also on sale for 99 cents. Grab both. I love them.
