This Space Galaxy pack's review will be very similar to that which I wrote for the main Indie Bundle Graphics pack, which I backed on Kickstarter in the middle of 2012.
Like sound tracks on Steam, you are not buying an application. You're buying a bunch of content that downloads to your system and will be accessed directly.
This bundle comes with a large amount of content (often broken into pieces, so you can assemble them for a much larger variety of funished pieces) that can be used in prototyping your games, finished games, websites, and just about anything else. Personally, I use it for prototyping my projects (and possibly hiring an artist for custom work, when all is said and done).
At the time of writing, there are almost 5,500 images in this pack, for a total of almost 4gb. For someone with no pixel-art talent, the character creator bundle is particularly useful for me. I no longer just copy and paste in ridiculous clip art from the web as placeholders or use big grey blobs to represent things - I refer to the art pack and pull out *actual* artwork to make *actual* characters.
Anyone who would scoff at the price either doesn't actually need artwork or has not dealt with commissioning or licensing actual artwork for games or other projects. I have. You'll usually wind up with a lot more strings limiting your use of the content and you'll pay more than this entire pack costs just for one piece of art work - whether commissioned specifically for you or just licensed from an existing royalty-free clearing house.
If you don't know if you need or want this art bundle, then you probably don't. But you know
if you do. This pack was clearly a massive undertaking for the artist and you're getting his custom work; not a bunch of random junk a cheap shareware company happened to be able to throw together. And for the price, it's hard to pass up, if you have a need for it.
