I missed it too, unfortunately. I hope it can be brought back but I feel it's probably not logistically possible. Ah well, I'm glad that a large amount of money was raised for an important cause by a reputable charity, and thank you to the developers that donated their hard work in a bid to help people who they'll probably never get to talk to or meet.
Hello! Has this bundle ended permanently? I just found this now and I really wish I could buy it, even for a higher price. I admire that it's for such an amazing humanitarian cause and I definitely feel like I missed out on some awesome games. Please let me know if you're considering re-opening the bundle! Thanks :)
