Just so you know, I'm well aware of the irony that I, in fact, did own a company, and that the only products it ever released were gaming material. I made many mistakes with that company that I won't be repeating, and it was best to dissolve it.
One of the mistakes made was that the company was made with no specific goals in mind - games, no wait pharmaceutical software, no wait software development tools, no wait games - and then when I settled on games I focused on just hardcopy role-playing games. (Even then I still bounced from games to other stuff and back.) Both the lack of focus and the overfocus were mistakes. My desire is games - only games, but many kinds of games. Board games, card games, role playing games, computer games. (I'll still tinker with writing that language, Lore, but it's a tool to achieve the end of computer games, not an end to itself. That's why I'm open sourcing it.)
There were many other mistakes I made in my company, but I won't go into them here, or at least not now.
