I definitely appreciate the effort, but there's quite a few issues. Some things behind the scenes, but I feel the biggest problem is the graphics and general lack of animation. Then there's the BBS posts which overcomplicate the animation a bit.
Part of the appeal of NG Sim was the simplicity of it while keeping the graphical environment realistic enough and pleasant.
This isn't a flash game, I don't think. So I don't know how much flexibility you have. I would probably recommend designing the graphics a bit more realistic.
I once made a Windows 98 environment in Flash, all done by hand. There's definitely an ability to create visually appealing graphics that would be suitable for this game.
