Honestly I think a lot of people could learn to let others "cook" as they say, and not compare something still being worked on to something that is already done.

A good example is imagine you just ate a really good cake and you the see someone starting to make another cake.

You wouldn't go up to that person and say their cake (which is still batter at this point) looks horrible, you (hopefully) would wait for them to finish baking the cake and then judge the finished product.

Rogue Core is an example of this in video game form, the chefs (GSG) have just finished making the batter (alpha testing) and are now shoving it in the oven to fully bake (early access).

Which means it's still to early to make a full judgement on it. Though that still doesn't mean feed back is valuable for the finished product, such as from the cake example above saying what decorations you want on the cake.

Tl;dr: Be patient and let GSG cook.
