Is BYOND the only...thingy, like this? I mean, there's Unity and all, but BYOND seems too unique. The language was derived from other languages, so it couldn't be the only one of its kind. Is it?
All game engines are going to have some key differences between them, otherwise their authors wouldn't have bothered creating them in the first place. Same with programming languages. Same with anything, really. I'm not sure what you're expecting to get from this question. A yes? A no? A comparison against similar software?

There are plenty of game making software suites out there. Some use high-level programming, some low-level. Some compile to byte code, others rely on VMs. Some come with software for creating art and maps, some don't. The list of features goes on and on.
AFAIK the BYOND suite is "one of a kind" in the sense that it's the only product that offers you the freedom of creating multiplayer games without having to worry about client/server networking and graphics rendering (among other things).

The benefit of this is that you can work on your game and get something working very quickly. The drawback is that client-side processing is not possible (currently anyway, but I don't see it happening in the foreseeable future).

Other game engines tend to give you more freedom on the client-side but have limited support for networked games.
I'm pretty sure BYOND's developing system is way different than others. I mean, I hate these annoying graphics coding stuff. Like Scratch, etc.
