We're going to try to have as much of our own "internal" feedback be on the beta forums as well so that beta testers truly become part of the team.
As the beta mentions when you load it, this beta program isn't a marketing thing or a "Demo", it exists so that players of this genre can help IronClad and Stardock craft Sins into the definitive real time space strategy game.
So with that in mind, here's a few items:
1) The constructor frigate should be something you can build from the frigate factory initially. I couldn't figure out easily how to build another one.
2) I should be able to select my construction frigate and move it around like any other ship. It's cool that I can click on an asteroid and tell it i want something built, but that should just add to the end of the nearest construction frigate's build queue. I should be able to click on a frigate and then right click on an asteroid to build (or select from the Construction Frigate's command window, select build mine and then click on the asteroid).
3) I'm not sure about the zoom out display on planets having a metalic looking wedge thing (for showing ships and structures). It seems to stick out. It seems like it would be more consisten to have it look like the HUD display still. I like the functionality, just not metal sticking on what one assumes to be a tactical display.
4) I think it would be a little easier to start out if the camera was slightly more over head. Right now, it starts nearly flat with the horizon.
5) Suggestion: The big ship players start out with shouldn't be able to leave the system right away. It could be an upgrade to the ship once you have the right technology. But that way, there isn't some capital ship running around right off the bat.
6) Suggestion: The pirate ships (and ships in general) take a bit too long to kill. I watched my big capital ship taking on pirates for several minutes thinking "Wow, this is taking awhile". It's not way way too long or anything but it seems the capital ship should have more of a punch (which is why I also think it shouldn't be able to initially travel around).
That's all for now. Having fun!
