I'm backtracking on Empyrion a little more again. This is from a Space Engineers fans point of view (me).
Having played the game now fairly solidly for a few days now (many hours), I'm surprised at how much they have put in since I last played some years back, plus how good it is.
So in brief, you can fly the Galaxy, no skybox, go/jump to any star you see and enter the system. There is a very good map system to use, 'Galaxy', 'System', 'Planet' and a kind of 'Proximity' map.
Scanners, although in this game they are called 'Detectors', are very good and give helpful info of your surroundings upto around 2km planet and 20km space. Getting around is easy but can be very dangerous.
Who knew (err, probably all the regular players), they have heat, radiation, cold, hunger, illness (eat the wrong food and you'll need a tablet), plus a few other things that will happily kill or injure you. Even engines onboard ship will hurt you when your too close to them if not insulated against. You have to be aware of all these things, which I find delightful in a game, especially for ship design. The player has to take so much into consideration.
It feels as though your living in the game, that is quite hard to find in many games. Not in a rushed way, but at your own speed, relaxed or anxious, its upto you. I don't follow story lines much, so play sandbox mode but in survival once your ready.
Choosing how to play the game is also a breath of fresh air. I don't like starting from a tin can, rock bottom survival. I prefer starting with a prepared ship, then put that over to survival and play the game from there.
So I built a ship, not finished but on its way and intend to put this into survival for long term use once finished. Until then I keep testing by popping in and out from Creative to Survival, you can do this using the dev console (ctrl + F1, then write 'changemode'). Also you can change back that way to.
This means I'm starting in a position more like X4 or Elite and so on. But the big thing I find as in Space Engineers, you can do this in a ship of your own design, which is usually much more challenging, fun and rewarding.
Once your in survival you can build your empire within that mode from your chosen start position, but at least you have your own ship to do it in.
There are a number of factions, mostly friendly a couple not so friendly. Trading is something I haven't done yet but I intend to give it a go once in survival for good.
Landing on planets, moons and so on. Although this is not seamless (doesn't really try to be), the more gentle your approach to a planet the better the transition is. Dive bomb the planet and the transition is very jarring. So I appoach and fly in gently and it is much better, although still very noticable.
The planets are a joy to be honest. Smaller than other games, but it sort of suits Empyrion. They are alive, or indeed dead for others, but ultimately have a nice realistic feel to them. There are weather patterns on planets, fly into fog, rain, snow and so on, makes for a realistic feeling.
Animals make sense here in the game, although dinosaurs are present and other nasties, they all feel as though they're at home on the planets, rather than put there for no reason other than to be decorative. The animal behaviour is basic, but it passes I think.
I haven't yet met many aliens, but overall watching YT videos about the game, they seem to have basic behaviour but again, not bad at all. They inhabit alien ships you find ingame. This means if you destroy a vessel enough to board her, you'll find crew in it that may still be alive, so smaller weapons are needed. They will fight reasonably well from what I have seen on YT, not got that far yet.
My thoughts on Empyrion are changing a lot. Perhaps I gave it a pass all this time because Space Engineers is so good for ship design and build. But I have to say, Empyrion is as good, if not and I can't help but think this is an apology to Eleon games, but their game is fast feeling better than Space Engineers in many ways. Wish the space/planet transition were better and you do have to tweak your ship a lot for a realistic flight feel, but you can get it with time. Gravity isn't as well portrayed as in Space Engineers, but it passes. This would be better with planets as part of the space your in rather than split and seperate, but you can forgive that for the other added things the game has.
I would say to any Space Engineers fan (I am), give Empyrion a go, it may surprise you as it has me.
Will it win you over. Yes, I think it could do, its doing it with me and I love Space Engineers, but that love may have to be devided equally.
Empyrion is fast feeling like a gem and I think this is the best time to play it after this last update. Give it a try and tell us if you agree or not.
Space to planet transition. If done gently is fairly good.
