It was only recently that we picked up the news of both GTA III and Vice City getting a fully working reverse engineered game engine, along with plenty of upgrades. Sadly, and expectedly, it got nuked from orbit.
Even though it required you to own the game assets, so you would have needed to purchase a copy of either to use the re3 and reVC game reimplementations that wasn't enough to satisfy Take-Two Interactive Software, Inc., the parent company of Rockstar Games. They've now given it the DMCA treatment, with the main repository and all known forks at the time to be taken offline on GitHub.
Sad but fully expected. Big publishers really don't like these sorts of projects, even though they can help revive their older games and perhaps even get them more sales. Copyright and Intellectual Property Rights are a legal minefield at the best of times, so the only way we may get this treatment in future is a fully clean-room reimplementation more like OpenMW for Morrowind or OpenRA for classic Westwood RTS games.
Perhaps now someone can pick up OpenRW again.
