There's a new Humble Bundle, named Kickstarter, because the games in the bundle were kickstarted. For a dollar, you'll get Guns of Icarus Online, which looks like a fun game, and I wanted to get it for a long time, but now I finally got it. Other two games for a dollar are AR-K and Full Bore. All of them have trading cards that you can sell on market for some cents to use on games or whatever. For beating the average price of currently 5$, you'll get a cool little horror game that came out recently, Among the Sleep and Retro Game Crunch. And for paying more than 13$, you'll also get Lords of Xulima and Warmachine: Tactics.
