Some of our TV shows and movies are produced in partnership with a studio that owns the franchise or intellectual property associated with the content. While we may have the rights to offer them for streaming, we may not be able to offer them for download.
Same goes for the bad guy missions being server side, if they were not server side they would be cracked. So what if you have to be online to play with these missions. There is nothing that can be done about it, you cant just run an emulator and play with your pc offline. So to make things worse Blizzard did not even add a menu to stop the client from connecting.
Another downside is that Diablo 3 server emulators require a bit of technical knowledge, so you will have to read the manual before playing with your favorite characters, and you will have to follow the instructions to get everything working smoothly. This is a big plus for the developers of the server emulator though, because they want to let everyone try the offline experience of Diablo 3.
So, if you want to play Diablo 3 without being forced by the publishers to pay every month for a subscription model, you can download this server emulator and try to play with the 3 existing Diablo 3 characters and enjoy a full offline experience right away. The problem is the lack of a support at the time of this writing.
Unfortunately, the developers who worked for a lot of hours on the development of this tool left Skidrow recently, which is why all the bugs and issues that were reported are still being worked on.
For those of you still waiting for Diablo 3 to be released on your platform, you can take advantage of the last patch and enjoy an offline experience, but you will be limited to only 3 characters and only certain maps (more than 3 maps are not available). As for the new Content (Hive, Villains and Mission chains) they are server side and you will have to wait for the next patch to be installed.
At the moment of this writing, there is no patch released. It is the same situation as with Act II of Starcraft 2, so this server emulator will only be useful while the patch is still in progress. 827ec27edc
