Hmm. I hadn't really sat and considered this point. Which game will outlast the others?
ED will survive for a few more years, it's still got a decent playerbase, a niche game that never had a huge playerbase at any point to begin with.
Prediction: 2027.
Starfield will do a Fallout4/Skyrim. Be VERY VERY popular for, say, 5 years, and tail off but still have an active playerbase after that with mods etc. They won't be the space sim audience though. Based on skyim 12-15 years,
Prediction: 2035.
I'll add NMS - it will continue for many years, perhaps 5-10 years before charging for something new. They made so much damn money they've been living off it
the lies for years so far and actually turned it into a very good game, even if I don't personally enjoy it.
Prediction: 2033.
And SC? A whale and his money etc (paraphrasing), so it won't end anytime soon. Or ... all of a sudden it will collapse in a flurry of legal action, backstabbing and financial accusations.
