Had a look at the email, and there is a lot of useful stuff in there, thank you.
I started doing some research into possible ways of recreating the environment, and it turns out someone started making an LDraw plugin for Unity. So my idea at the moment, is to recreate the models in LDD, or Bricklink Studio, then I can export them as LDraw models, which could then be imported into Unity. I could start working on that right away. I've seen someone on this forum has already built a lot of the models using LDD, so I might get in contact with them.
I also wanted to make a list of the various game mechanics in LR2, like the action playback, and how the camera locations are picked. That sort of stuff. If anyone has info on these things, I would appreciate the help.
