Hi Denki - while searching for info about the game Graphics options, I spotted that the term "AutoNaut" is already registered commercially as an autonomous unmanned sea vehicle... http://www.autonautusv.com/ - You are probably already aware but just in case you need to do a check before registering the final version of the game title.

thats a cool little boat.

:) Thanks, yes we saw it before.

Since they are two totally different fields, I doubt it will be a problem. But still a consideration for things like registering a domain name and getting good search results in Google and Bing.
