Not really a such thing as deep space. You're either on a planet or in space nearby and in between the planets, not much else. By nature, with procedural generation you're going to wind up finding things that look extremely similar before too long. The game could benefit from more variety because once you've seen about 30 or 40 planets, you've seen most of what the game has to offer on that front. For me, there's a handful of looks that I seek out and like to build bases on, so that's what keeps me going - seeing how creative I can be in my favorite locations. The game is like 20 bucks on CDKeys so it's worth it. Early game and learning the systems is a grind but about 30 hours in you kinda hit that critical point where you have everything you need or can easily get everything you need. From them on it's just deciding if you want to start optimizing your ships and stuff.
