I have Terraria. I have Minecraft. I have the Landmark beta. I keep trying to convince myself that I'll enjoy these sandboxes. And yet every time I do, I find it hard to get into them. And I know the problem is with me. I guess I keep trying because it's hard to come to grips with the fact that I'm not creative.
Initially I felt the same way about terraria but I pushed myself to stick with it and i'm glad I did really enjoy the exploring part. It's very free or stress free there's no pressure to do anything which is why I stuck with it. As far as being creative and building something haven't done much of that myself i'm just really enjoying the running around finding new stuff.
Also there's cute bunnies who who doesn't like cute bunnies?
