markx182: If they add Joe Danger 1 and/or Rogue Legacy and/or Gone Home I'll be sold.
I'm wondering if they added Joe Danger 2 to drive sales of the first one. Seems a bit odd to leave it out of the actual bundle. If they don't add JD1 as a bonus, I guess we can consider this suspicion confirmed. A lot of publishers are exploiting the completionist urges of gamers at the moment to drive sales - look at the Origin Bundle (no Dead Space 2, no Crysis 1) and the WB Bundle (Batman games - including DLC - to drive sales of Arkham Origins, Mortal Kombat Kollektion to drive sales of the 2011 Komplete Edition).
And we all know that they added Runner2 as a teaser for the rest of the BIT.TRIP series, which is being prominently advertsed on the Humble Store right now.
By the way, it's worth being in mind that the offices of Hello Games were recently flooded as a result of the storms in the UK, and they lost more or less EVERYTHING in the way of equipment and furniture as a result, and their insurance won't cover it. I don't reckon that the inclusion of Joe Danger has anything to do with that (the inclusion was probably planned a bit before that), and the bundle inclusion was probably intended to fund their upcoming game No Man's Sky, but it's certainly worth bearing in mind if you wish to support them.
