Hydrocraft Classic is the original modpack. This modpack has over 120 mods and therefore it is recommended to have a good computer with a 3.00 GHz CPU and at least 4 GB of RAM (8 is recommended). This modpack is also no longer supported and there won't be anymore updates unless there's a game breaking bug or I no longer have permission to include a mod. Do not host a server unless your computer has more than 4 GB of RAM (not including running the client along with the server). This modpack may be very unstable so make sure you always back up your worlds, I am not responsible for any damage done to your world. You have been warned.
