Looks pretty decent. I've already got the Ball (which is bloody good) but the others are interesting enough to justify dropping a few quid on this one.
Well, I have to admit the games look kind of interesting. And with a Pay What You Want approach I might be tempted to give them a try despite my dislike for Steam's client-based service. But if they'd manage to convince the publishers to add direct links (to hopefully DRM-free) version, it would increase the chances of me actually spending money on it.
This one looks really promising. The fact that they're at least trying to get their games drm-free as well due to people commenting is a good indication that they might deserve the money.
UPDATE: 3 of the 5 games will have a direct download PLUS Steam keys, 2 will only have Steam keys. Of the 3 with direct download, 2 will be PC only and 1 will be PC and MAC. Official promo video will be released 04:00 GMT 14 February 2012
Also:
The incentives themselves, if achieved, will be WORTH WAY MORE than the price of admission... and no interoperability issues with the incentives... btw, sneak peek of the incentives coming on Thursday.... hehehe
