It is in the "pre-alpha" stage right now.
Currently you can view ships that you have purchased in your hanger, and sit in the cockpit, things like that.
In the next few months they will be releasing the Dog Fighting Module. They indicated they wanted to get in out this year come hell or high water but there are hints of delays.
Currently no way to specifically "credit" ToG when you pledge but guild organisations are coming.
Personally, for a game that has a full release over a year away, the community is huge.
A few points to consider
If you are even thinking about, I would drop at least the minimum $40 for a basic alpha, beta, ship package.
There really isn't a need to spend more than than at this time unless you find a ship you really like as everything that you can buy now you can earn in game. In addition, the ToG guild has WAY more ships that pilots so odds are you will be able to easily find a crew position on a larger ship to check them out.
Of course, that advice is "do what I say, rather than do what I do" as let's just say I've spent orders of magnitude over that amount.
The developers don't have a publisher to tell them how to evolve and create the game, they have us. It's pretty cool seeing it evolved based on the feedback they get.
So take a look at the ships, watch the videos (google aroa, origin and hornet commercials), strap yourself in, and join the fleet!
