I like the idea Flyfalcons.
Don't let the naysayers get you down... I certainly didn't. I've created many .ork files after being told it was a bad idea. I've had the satisfaction of knowing that some of my files have been viewed over 100 times. Basically, if they don't like it, they don't have to use it. There's nothing saying that they MUST download the sim here, or anywhere else.
Rocketreviews .rkt files IMHO are a real crapshoot (emphasis on C**P). Some are fairly decent, but WAY to many of them are practically useless. There's no way of knowing who created the file you're looking at. You have no way of knowing if this is one of the decent sims, or one that the number of fins are right and the body tube lengths are right but everything else isn't (like the name of the rocket... For example...The Estes Leviathan I downloaded there that was tagged as a Ventris).
Here... You will likely know immediately who created your sim (they'd be the one who posted it). You'll be able learn whose sims are pretty good, and perhaps what people you'll want to look out for on the field (if their rocket is as bad as the sim, LOOKOUT!!!). Also, here you can edit your post, to update your file, or post a reply to someone's sim. RR's site you can't. You can also post variants in one place, instead of having to hunt for another sim in a sea of sims. Additionally, along with the file you can provide more information here. You can tell people about what compromises you may have had to do to achieve the results you have, or add images to show neat little features...
Yes... I really did add wings to the wingnuts, and now have a sim of an eyebolt.
Sure, here the search function might be a bit more problematic, but it is what it is, and for the most part it seems to work for me.
