So first off, yes the game is still very, very early in alpha stages. However, it is still a playable and enjoyable game and has loads of potential. This is the best space rpg game I've seen since Microsoft's Freelaner (still the best by far, even after more than 10 years). The gameplay is for the most part a good balance between a complex dynamic economy (similar to EVE) and the relative simplicity of combat and manual ship navigation (such as Galaxy on Fire 2). Be warened though, this game has a truly massive learning curve, and besides the downright pitiful intro tutorial, all they give you is a "pilot's manual" which is way too wordy for anyone to read. So if you do decide to dive in to this game, be sure you have more than enough pacience to do so. If you need help, the best way to get is just to ask the other players in global chat, they'll help you out.
This game advertises itself as an MMO, but right now in the early stages there is nothing massively multiplayer about it. It's a good day if we get more than 10 players online (there is only one server for the US), and even then becasue of the vastness of space it is unlikely you'll stumble across anyone. The lack of a good system for players to trade goods and credits between one another is also a glaring flaw in the game's social ecosystem.
While the gameplay is good for the most part once you get the hang of things, there are a couple snags worth mentioning. Navagation though space is based on a 2D map. You use this map to navigate your ship to certain instances, such as stations or asteroid fields, where you enter a 3D interface (the one shown in the screenshots) and fight other players or bots, mine asteroids, etc. This 2D map, sector based gameplay can be a little boring at times, although I've heard rumblings that the dev's are going to replace it sometime soon. Once again, this game is only for people who have the patience and time to deal with it.
Now on to some good things. The graphics of the game are great when in 3D space and combat, while sparse, is involved and engaging. The complex and dynamic economy allows for trading to be very profitable, and there is also a large variety of tradable goods. For those who have been looking for a good space rpg it more than delivers.
Bottom line, it's a solid game, but with much room for needed improvements. I would recomend this game to anyone who has the patience to tackle the learning curve and the at times slow gameplay. Don't be silly though, just buy the $20 colonist pack. All explorer and founder do is give you some slightly modified versoins of ships that are available to everyone in game, and a small amount of extra credits, of which you can earn twice as many trading comodities in an hour. This game isn't worth more that $20 right now.
