Can I use code from a computergame that is owned by a company A in order to develop my own game at company B?
<p>I want to develop a game with my own company, lets call it Indiantruckaimulator, that is very similiar to the already existing game, Eurotruck simulator. I would greatly benefit if I could use their Code/Software and simply add some changes.
Is there a way for me to get access to that code, preferably through colaboration :), to be able to build upon that?</p>
<p>Thank you for your time and answers!</p>

<p>You ask permission, preferably with legal counsel to handle the details. It really is that simple.</p>
<p>Unsurprisingly, most companies don't want to give their code away- especially to a competitor. If you even get a response, they will expect something in return i.e. money.</p>
<p>Realistically though, it's unlikely they will respond, much less deal with you.</p>

<h2>Code is copyrighted</h2>
<p>The code is copyrighted. You need a license from the copyright owner to manipulate it, if you alter it to the extent that you create a derivative work and do not qualify for Fair Use or a similar exception (see below).</p>
<p>Creating a game with a different map clearly is a derivative work.</p>
<p>You can only get that license from the company that initially made or currently distributes the game which code you want to use.</p>
<p>If they don't respond or don't want you to use their code, you can't use their code at all.</p>
<h2>But... fair use?!</h2>
<p>There are <strong>some</strong> exceptions to needing a license, like fair use. However, those are generally not available for making a competing game.</p>
