Humble Bundle are always going to be of varying quality - sometimes including only a single quality game with some bonuses, sometimes of no interest whatsoever - but the latest, titled Jumbo Bundle 2, is quite the bargain.
For the low, low price of whatever-the-hell-you'd-like you'll get space 4X Galactic Civilizations II with its expansions, side-scrolling undead violence-applier Deadlight and isometric action RPG The Incredible Adventures of Ven Helsing. Beat the average price however ($6.32 at the time of writing) and you'll also receive 2D survival exploration Terraria, combo-heavy high-skill fighting game King of Fighters XIII and the story-spawning strategy-RPG Crusader Kings 2.
The pay-what-you-want games are nothing to sniff at. GalCiv 3 is currently in Early Access beta (more on that later today), but GalCiv 2 remains one of the best 4X strategy games ever made. Here's ex-journo now-dev Tom Francis' excellent Gal Civ 2 war diary, which I'm reliably informed is required reading on the game. Meanwhile, Adam took a bite out of Deadlight in 2012 and found it acceptable while John had his eyebrows continually raised by Van Helsing.
If you've more money rattling around your internet wallet, beating that average price nets you the aforementioned better three. Terraria was one of the RPS games of 2011 and has been massively expanded through major patches 1.1 and 1.2 since, with still more to come. King of Fighters 13 is a beautiful beat-'em-up and regularly played competitively; here's a video of the EVO 2013 top 8 tournament, one of the best ever, for all you'll need to know about that game. And Adam is always ready to preach the virtues of Crusader Kings to the masses; the latest sermon is his ode to the game at the end of 2013.
Finally, if you are Godking Moneybags, richest person of all the internet, you can go for the full $15 option and get the HD remake of Age of Empires II and the Age of Empires III Complete Collection. They were never my favourite RTSs of their eras, but they literally made Brendan so they're classics/horrors.
There's also the usual tease of more games to be come. Grab as much of it as you'd like over at Humble Bundle anytime over the next 12 days.
