I think that that's actually a pretty cool idea to be honest. Probably sucks at first but still
It makes things interesting honestly, I mean when you think about it, going to an alien world you aren't going to know friend from foe so I'm assuming thats that they are going for with the random generation. Some of the sound effects are downright silly though, I remember coming across what looked like dinosaurs but the sounds they made were like someone sticking their tongue out and making a fart noise.
