No. No no no. Sue them. Sue them dead. Where product and brand robbery thrives, developers wither. What's the point in working hard in developing a game (or anything) if all your hard decisions are just going to be copied in a matter of weeks? Why bother? There is certainly an evil side to copyright, trademark, and patent, but these weapons have a place on the side of justice too. Unprotected developers—at least those for whom the money or glory has significance—will give up eventually. When imagination doesn't pay off, the only ones left will be the unimaginative, the copy cats, the cloners. Sue them, for our sake if not yourselves.
