The server would also have Perham, which I think you might prefer over alien due to its tough environment. As for suit only, I have bad news - I'm strongly considering disabling signal sources, because they just feel very gimmicky to me, kinda like Hunger Games drops. That doesn't mean you couldn't do suit only, but it would be harder. I really like the idea of "space is big and empty", something the default encounters doesn't really provide. It's one reason I'm considering making custom, persistent NPCs that follow shipping lanes.I’ve tried both, and I’m not a fan of either. They both pretty much kill a starting engineer. Of course, it’s YOUR server, so if you want the Alien Planet to be a PvE challenge, go for it. Depending on settings, I’m almost tempted to do the “suit only” spawn.
I still have a LOT of playing around to do. My goal is to make it SE a more realistic experience, but not ridiculously challenging or boring. That sweet spot is going to be pretty narrow may require some work to achieve.
