&gt; What will Blizzard normally do if they accuse me pirating their assets?<p>Most likely, they will tell you: &quot;shut it all down or we&#x27;ll sue you into bankruptcy&quot;.<p>I recommend taking a look at <a href="http:&#x2F;&#x2F;opengameart.org" rel="nofollow">http:&#x2F;&#x2F;opengameart.org</a> for free (and legally free) placeholder art you can use instead, and changing any names ASAP to remove &quot;Starcraft&quot; and anything directly based on the unit names, etc. (Referencing Starcraft in the README or other such things should be fine, though.)<p>For example, &quot;SpaceCombat&quot; with &quot;Troopers&quot; and &quot;Knights&quot; and &quot;Hordelings&quot; and different art and music for everything would be fine, legally, even if the actual game mechanics were exactly the same (as long as it&#x27;s your own code implementation of them).
