Honestly, I think it comes down to having a few games that are "hits" (meaning ~100K audience instead of the ~1K you have in our incestuous community) and having those games mention that they were created through BYOND. As such, we are working on features (standalone & website-games) that can make the initial exposure for games easier, and are working with a few users to get them marketing these games.
Thats certainly a viable way to go; in the utopian world, after the initial games begin to pave off, you'd want a somewhat stable release of a few games to keep BYOND on the radar occasionally.
I was probably one of the more.. vocal individuals, when it came to the whole 'We need to change BYOND so it can be a success' parade, a few years ago. And while I adamantly believed that the things that were being suggested were a must, in the end what will keep BYOND afloat is a coherent business strategy and a way to market hit games and get noticed, on an Internet increasingly spurred by one-hit wonders and reddit stories.
People get so caught up in the limitations of the language that they don't even realize that these games can be successful with the tools we have now. NEStalgia had a brief moment of internet success thanks to being mentioned on a few articles and during that time got a lot of users and made a lot of money (with some carry over even to this day). Yet the number of people who even saw those ads during that time was negligible compared to the potential audience. If a game can get on some major portals or get prolonged exposure, it will get users, and it will make sales. And that will reflect well on BYOND because some percentage of those users will want to do the same thing.
People need to stop comparing BYOND to general engines like Torque or Unity because those are catered to a different sort of developer, one that generally has a lot of programming experience prior. That is why they can get away with selling their tools for hundreds of dollars. BYOND is built on the belief that there are lots of creative people out there who may not have a lick of programming experience but want to make their ideas a reality. Push those people to these other engines and they won't get anywhere. But with BYOND, there is actually a real chance because the barrier for entry is a lot smaller. And I do believe someone with very limited programming education could make a game like "Words with Friends" in BYOND.
