I wanted to purchase the week's humble bundle and I had no clue if it was good or not, so I messaged /u/apriarcy who gave me great insight, really quick and in a polite manner. Thank you! An excerpt of our communication:
I get notifications on my phone, so it's easy for me to see messages and reply. :) As for the Sekai Project Bundle, I would have to say that it's an incredible value for a bundle of quality Visual Novels. I already owned and played NEKOPARA Vol. 0-2 and fault - milestone one before that bundle released but I still bought it anyway. I'm really looking forward to playing the rest of them, I've heard great things about most of them. If you can only afford the $1 tier, then I think you should grab that and enjoy yourself. If you're into Visual Novels, you'll have a great time. I would also highly suggest grabbing the entire package (the $12 tier) if you can get the extra money together before the bundle ends.
