We can't create a board for every single project someone makes. However, if this starts to really make progress and becomes comparable to engines like L2Player, Loap or SuperLemmix (all of which are considerably less popular than say, NeoLemmix, so it's not like we're setting an unreasonable bar here) we can definitely consider one at that point, especially if it's getting to the point where having one topic for it is becoming a bit too cluttered. I don't think we're at any risk of that yet though, since at this stage your post and this reply are the only posts about it.
It was also pointed out to me that you've announced several projects, then never talked about them again. It feels like you're kind of just thinking about what might be fun to do in the moment, rather than committing seriously to any projects. I get that - I was like that too at one point in my life. Even the relatively simple projects you see here though - even many of the ones that don't have a board - are things people have put a lot of work into for months or even years. NeoLemmix and Lix, as the biggest examples, have been worked on by their developers for over a decade (might even be close to two decades for Lix now). Most people don't even create topics, let alone get boards, for something that hasn't yet progressed beyond a vague idea they think "might be fun". Maybe it's a good idea to spend some time thinking about a project you can really commit to (and that you can actually manage most of yourself, rather than asking other people to do the biggest parts of it with your own input being just the ideas and smaller aspects), spend some time working on it, and when you're really starting to get somewhere with it, start sharing. Yes, there are a few people here who'll start talking about projects when they're barely even ready to reveal a name; but these are people who've been here for a long time, have a track record of delivering on their projects, and most importantly - these people do have far more than just a name/idea, they're just choosing not to reveal it yet.
