This is one hell of a bundle. Partly because you'll get 15 Steam games for only £1.33, but also because several of them are excellent. AI War is great. Bionic Dues is great. Skyward Collapse is great. Tidalis is great. A Valley Without Wind is divisive... but I think it's great.
Those are all Arcen Games titles, mind, while the rest are all over the place quality-wise. Still an absolute steal for less than 9p a game, thanks jaystan!
