I guess a lot of it is impatience, but as much as I enjoy Exanima, I want a final game to play. Not a beta, or a testing ground for them, but a complete game (SG).
Sometimes I do not enjoy playing betas because I feel like I'm a guinea pig (that's pretty much what we are, right, and I do understand people playing alphas and betas is very important to improving games, squashing bugs, etc.), but it can sometimes alter my enjoyment of the final game for a variety of reasons.
I've been dying for a game that is truly based in physics, creating unique and original fights, situations, etc. I just find myself not playing the beta as much as I should as I'm worried it's going to ruin my enjoyment of SG when it comes out. So, maybe this can help provide context in why I'm so eager to have an idea when this game is coming out.
Q4 2016 would be nice. Q1 2017. Give us something!? lol
