If a subscription was asked I 'd feel completely tricked into this game. Especially after solo mode not being implemented properly ( I m one of the few not always online...).
After all we paid for the whole game experience. Imagine if Guild wars 1 or 2 was asking for a subscription after the first year. People would just abandon the game en mass.
The way to keep people in the game is expansions. More ships, a completely re-implemented mission system, maybe some sort of solo scenario, some kind of end game?
I do enjoy the game as it is, it is already better than most games I 've backed in alphas and betas, but a sub? There is no reason why people would stay, or even ask their money back! They did it for solo being cut out of the final product, this would be even worse. The deal was one time pay to own your game copy. How would such change it legally stand even? It would be like asking our game copies back without a refund. "Like" is not even needed in that sentence, it would be exactly that.
You buy a house, then the previous owner comes over:
-Hey I know you bought the house but I decided I should rent it instead. So lets forget you ever paid for it and pay up...
Anyway, expansions, sure people will pay for as long as they deliver what's promised. If it cannot deliver, well, too bad for Frontier and us playerbase. We both move on to the next game. (But please make it awesome!) Cosmetic microtransactions? Yeah why not? Python coloring looks hideous otherwise and that new graphite paint job looks cool. Frontier needs a bit more creativity with the kind of cosmetics it can sell and they ll have a sustainable economic model.
Why is subscription even discussed??? Online DRM already prevents piracy and the playerbase is so old it must be the most mature playerbase of all games with any kind of online mode! (Maybe chess beats elite on that...?) Maybe people worry about the console crowd getting the game and how they ll affect the current community? I don't think subscription keeps immature players out of the game. It's actually the game's character that does. And that is well set IMHO.
