It's interesting, but the licensing of the assets is very important to us here.  If they aren't freely licensed/are edited from proprietary sprites, then it really isn't much use to serious game devs of any stripe.  If you wanted to adapt it to use only open source assets, there's a fair amount currently available and I imagine you could get quite a few further contributions as well.

Apologies for the misunderstanding, but I don't think your post was as clear as you think it is.  For instance, while you do list some sources of graphics, you don't say what license they are made available under.  Similarly, the sentence 'I cannot add images that require a license unless I can get that license free' really isn't perfectly clear; I kind of assume that you mean 'I can't add images unless they're CC0 or otherwise freely licensed' but there are other ways of interpreting it as well.  And sentences like "NOTE: For entertainment and my personal use." muddy the waters a bit, though based on your last post I assume it's more of a statement of purpose.

Anyway, I'm glad you've gone out of your way to get permission.  Are the base sprites just CC0, or are they under some other license?

"Also? chibi sprites in a serious corparate game? Time to switch companies. This for for people who are new to programming. These are temporary and anyone who uses them in a full finished game would be severly limiting their graphic abilities."

I'm also not sure what you're getting at here.  Nobody brought up 'serious corporate game,' (though there are plenty of serious professional games which have used chibi sprites).  The quality of the sprites you pictured is quite decent, and would be adequate for some games.

from your post. I just took 'of any stripe' to the max level."

Gotcha.  I actually just meant to cover open source and commercial (ie: small indies).

"The base sprites cannot be used by the end user. No permission, from me or the original image holder, is given to use the base images. Only the compiled sprites are allowed to be used freely. If someone planned to use the base images they would require a license of their own. I was told by Enterbrain that the base paid RTS images cannot be provided if I choose to release the source and that I must exclude them. I can only release the base images in the compiled program."

This, alas, is the crux of the problem.  This sort of mixed licensing isn't really a "free" license in many senses of the word, and it's really hard for a dev or artist to navigate exactly what it means.  EG: you can use the output, but not the base sprites.  So does that mean you can distribute the base, but with say a bit of hair, as part of a freely licensed game?  And what if an artist went back and then edited the hair back out?  Things like that make devs and artists alike really nervous, and make it hard to use assets licensed this way at all.

Generally it's best to stick with things that are explicitly licensed under a widely used and recognized open-source license, especially one designed for art.  While a number of these (like CC-By-SA) have headaches of their own, at the very least they are consistent from one asset to the next and generally a known quantity. 

We actually do have a couple of RPG bases with accessories which are freely licensed, including the LPC base (http://opengameart.org/forumtopic/universal-lpc-sprite-sheet) and a 16x18, 8-bit styled base (scattered about in here http://opengameart.org/content/oga-16x16-jrpg-sprites-tiles).  While I can understand not wanting to go through and rework the program to use different graphics, what you have is neat enough (simple, effective interface) that if you did it would probably be a hit.  There are a few other features that would help (eg: dynamic recoloring of assets in program), but it would still be neat even without that.

Instead of having the base sprite in multiple colors, I'd rather see one base sprite and a set of selectable palettes that can be used for multiple base sprites.

My dad had a stroke over the weekend and I haven't been around to approve posts.   I apologize for the inconvenience.

Also, for the record, we get a tremendous volume of spam attempts, so as much as I'd love to turn off the spam filter, I can't do it.  If I did, we'd be inundated with far more spam than I could manage.  It's unfortunate that it occasionally gets false positives.

Done.  Also, I tweaked the spam filter a bit, so hopefully it won't give you any more trouble.
