[gush] Nifflas is a really positive, understanding and accepting individual, in my experience. It's worth noting he's not laced Saira with DRM and has no means to limit you from installing it on, even, your friends' PC's. He also seems to share my view of Steam (being that it makes the life of honest users a nightmare, while pirates can still find ways)
Saira is run as a (pretty much) purely honour-system, rather than a more typical piece of sold software. Nifflas is a very decent person, and I think that promotes (at least in his core fans) a feeling that he deserves to be treated with equal respect. One of the most common responses I've seen to Saira is, "It's not long enough that I feel it's worth the price, but considering how many games of his I've played and loved for free, it's a small price to pay..."
This is likely grossly misquoted, but I hope the underlying implication comes across. Nifflas has released (in my opinion) some of the most enduring indie games that have ever been coded (especially once you add in the fan-made elements) and asked nothing for them for that entire time. Heck, didn't even allow the possibility of reimbursing him for the (months..) of joy I, for example, had from KS.
There are, IIRC, two developers I respect as much as Nifflas' for their selflessness. It's a rare quality in any person, and in a person who provides you with enjoyment it's a blessing. [/gush]
I'm sorry... this is very emotive and I'm sure Nifflas himself will find it pretty uncomfortable, but I believe him to be a special sort of person, and would believe the same had I no more input from him than forum posts.
