A good name can't guarantee success, but a bad one can certainly lead you to failure. (I can't see your logos, so can't comment on those).
It's worth putting a lot of thought into: hopefully that name will be representing you and your work for a long time. As was pointed out above, easy pronunciation and spelling are very important. Blizzard may not immediately conjure up images of video games to someone hearing of the company for the first time, but at least they know how to say it and how to spell it. It's also easy to remember.
Names of gaming companies/publishers that I can think of off the top of my head: Blizzard, Bioware, Square(Soft -Enix), Black Isle Studios, Elephant, ERS, BoomZap, Blue Tea Games. I also have names like Obsidian branded into my head for all the wrong reasons (rushing out two unfinished sequel games).
The one thing they all have in common: if I read the name out loud to someone fairly fluent in English, they can write it down spelled correctly. In this age where people expect to be able to type www.<company name>.com and get to your website, that is VERY important.
