Humour me here...
I was wondering how much it would cost to develop a new Lynx game. Imagine I came into some money and wanted to make a "retail" style game (something comparable in looks, length and gameplay). Print up boxes and do a short run of cartridges. The goal being to, at best, try to cover cost. So, as the money-man... in this hypothetical situation, I'd need all the development done by someone else etc etc. Let's also assume there was a concept/storyline and so on, we just needed the programming/practicals done.
Also, I am sure there are many challenges and "piece of string" things to consider. Let's just think top-level, and for the fun of it. I guess I am thinking along the lines of the reverse of what happens with homebrew, where someone chips away at a game, and we all sit here hungry for it, hoping that person has time to progress it. What if we planned it intentionally with an idea of cost and timeline and did it as a project.
Is that something that's even realistic?
