Well after playig the beta 2 i'd like to start saying that I find Sins its a game with a great potential but against what people have said, I belive graphics can be far better.
1. Movement of Ships is not quite realistic, they are always moving on a plain axis so I can not have a complet 3D sense. Is there any way to make ships move verticaly? Even when two ships or more find at the same point they have to give way to the others before continuing their ways, not very real in such a hughe space.
2. I also miss some space trash after destroying spaceships, parts of the wreck or something. They just explode and thats all.
3. And finally, in my opinion, ship design is quite basic too much squared, perhaps some sort of soft lines would look better.
4. And scale, I do think a capital Ship or a cruse should look much bigger than frigates, this would justify the difference in speed movement.
There are other space games that are quite better than Sins in this sense so far, like Homeworld 2, or if you remember Haegemonia.
Hope to be of use.
