You can license KEngine in two ways:

Free Licence

If you are using KEngine or any of it's components (KGraphics, KSound, KTheater) for personal entertainment, investigation or for developing any software that won't be charged in any way, then you can use KEngine for FREE.

In this case you accept this agreement, you are required to include the KEngine name somewhere in your product (loading screens, main screen, credits, etc). You can include the KEngine logo in your product also.

If you like this kind of license, please remember that I have worked very hard in this libraries. I have many ideas like finishing the Isometric engine that is based on KGraphics, moving the engine to 3D and building network support. All this consumes time and money so a contribution would be greatly appreciated to support the author (me) and the development process. Finally, if you decide to purchase any KEngine Commercial License, your contribution will automatically be deducted off the price.

Commercial Agreement

If you would like to use KEngine or any of it's components (KGraphics, KSound, KTheater) in a commercial product then you must pay a fee based on your budget or commercial plan.

The following prices are a reference. In any case you shoud contact us for setting a more detailed agreement.

1. Multiple shareware titles for individuals/hobbyists $100
2. One site license for unlimited products $1,000
3. Engine resale (full source code) $5,000

Any license will be approved case by case to verify if they qualify as shareware product. Sometimes, if the product you are developing will contribute any altruistic cause, the license fee may be reduced.

Meaning:

Multiple shareware titles for individuals/hobbyists : $100.00 US. The licensee must be an individual/hobbyist and not a registered business or company with more than 1 employee or director. A shareware license is available for any number of shareware / budget titles. Independent groups and some proyects can qualify for this license. This license should be purchased for each programmer seat.

ONE Site license for unlimited products : $1,000.00 US. You can use KEngine for as many products as you want. This license covers ONE SITE and ONE company only. You can't lend the license or anything like that.

Engine resale. $5,000 US. This option is available for companies that would like to modify the KEngine to match their exact needs or to develop products that will be sold to 3rd party companies (like a modified game engine). End users of KEngine based engines get the right to use them without further payment to us. This option comes with full source code.

In any of these options, NO ROYALTIES are required. You dont have to pay any more. No accounting and all that stuff.
