I don't completely agree with Greg's points. Firstly, I don't see why Jakerpot doesn't sound appealing. It's original so what's the deal? And how do you even define appealing? It's so subjective that you can't possibly please everyone. I don't think such things as "bad/unappealing company names" exist. The important thing is that it's memorable. Jakerpot Games is a name you don't forget in an instant, unlike boring names such as CreatIV Games.
The thread's over, but I thought I'd respond to this post to clarify my position. Since you want to make a company name that appeals to your customers, you need to consider your market. If you're creating games for adolescents, something like "Toilethead Productions" could fly. If you're creating childrens' games, you need to bear in mind that their parents will probably be buying the games for them, so you need to come up with a company name that appeals to parents. Do you begin to see what I'm saying?
Anymore, while thousands of new companies are being created, you need to rely on something other than a catchy name to help your company catch on. (which is why we take into account SEO for the company name, market appeal, etc.)
Like I said, though, for a company that's going to be making free games, all this is probably far beyond what you need to consider.
