              </p>
              <p>
                The Ecosystem License allows AeThex development teams (specifically our GameForge
                arm) to use your track for free in non-commercial projects. This includes:
              </p>

              <ul className="list-disc list-inside space-y-2 ml-2">
                <li>Game prototypes and development</li>

              </p>
              <p>
                If you want to license your track for commercial use (outside our ecosystem), you
                can set your own price on the NEXUS marketplace or negotiate directly with clients.
              </p>

                Our CORP arm can help negotiate high-value commercial licenses and connect you with
                enterprise clients.
