I'm gonna be frank here, this game seems a lot like Terraria. Starbound looks way better and interesting though with it's unique innovation and tons of features and weapons. Anywho, let me get to the chase. When i played Terraria, you always knew you were safe in your house (unless some 1km long robot worm was spawned..), zombies took eons to break down the door, and that was pretty much the only way for monsters to come in, and even after they entered your house, it was easy to avoid them if you had more than 1 floor. I wanted more danger, wanted more insecurity and a sense of never actually being safe in my own house. I really wanted many different mobs capable of tearing your house down to the ground, being able to bomb my house and leave gaping holes for hordes of monsters to enter through (or being smart enough to exploit), forcing you and your friends to defend the house, making a last stand or eventually had to run for your lives, leaving your house because it is no longer safe. Huge house-destroying waves and waves of mobs events once in a while when it gets dark would be the sweetest thing ever. (Numbers of monsters spawning depending on the difficulty you set it at, your gear, your level, the amount of time played.. SOMETHING! I NEED ACTION, I NEED A CHALLENGE!!!!) Oh and also, a new mob suggestion: Mobs that sole purpose is to eat the blocks that players have put up. (Like a house), but otherwise ignores the blocks the world started with, like the dirt on the ground or the trees.
