Astroneer last night was fun but hitting crash bugs over and over was so very annoying. Big R understandably "fatigue-quitted" over them. We decided to do less land-training and more deep-cave diving for research, and we found it was stable. We got battery research, EMW managed to make a Moon base using the ship as a starting point and I became a ferry pilot to move resources from Terran to the Moon. I got a crash report now and again but it was certainly more fun. [Big R - I found the land train and your stuff and returned it safely to base].
This was avoiding areas of the engine that are clearly not right. Big R and I (as clients to EMW's host) were both hitting bizarre physics engine bugs that would often kill us.
When a game becomes Early Access I think it should be in a Beta testing state, rather than an Alpha. I think Alpha is too early. My expectation is that the game is largely working but the general balance and feature set might change. I think that most others expect it to be playable for an evening without several crashes. Features (such as land trains or rovers) shouldn't be included if they are not stable.
Astroneer has a great big disclaimer up front saying that it's "Alpha and in a dodgy state, so don't complain" but that's not really good enough for me.
My worry is that a game that has so much promise and when working is lots of fun, will ruin itself by having frustrating bugs that keep you dropping out. You then become fed up with the game, regardless of the warning messages, before the game has had a chance to sort its life out.
Unless Astroneer has a big update, perhaps next week we elect to avoid land trains or play a spot of Unturned, which has been stable for some time.
