Hello there.
I'm about to release my game
Flow Motion (finally). Since it's my first finished project I want to keep it free (also, I doubt anybody would seriously consider paying money for this

). However, I know almost nothing about legal issues.
For instance, most games seem to come with an installer that, apart from installing the game obviously, requires you to accept certain terms of use. Is something like that necessary, or at least recommended? Like to make sure the player doesn't sue you when his graphics card explodes while playing your game?
Websites usually require an
about page including name, adress and contact information of whoever is responsible. Is there something similar for video games? Do you need Credits of some sort?
On top of that my game contains an interactive link to my website (i.e. you can click on it and it will open the site in your browser), might there be a problem with that? Most websites seem to explicitly state that they're not responsible for the content of any outgoing links. Would I need to include such a disclaimer into my game?
Sorry if all this seems a little random, just a few concerns I've had in mind for the last couple of days. I'm not really sure how to google this stuff, searching for "things to know before releasing a game" doesn't exactly yield many results. And since we're talking about the release of a free game, I didn't exactly intend to get a lawyer.
I kind of doubt that there are any actual, strict laws on this stuff, considering that there are probably thousands of free games coming out each day, and I haven't heard of anybody getting sued for not having a proper credits screen in the game. But you never know...
Thanks in advance!
