When you purchase a NEStalgia subscription you agree to the ToS that states that the purchase you're making is for the product as-is. That's not open to interpretation; that's a fact.
That's nice that you have an opinion though ;)
Please take notice of the fact that I'm not subscribed to your game.
I don't agree that is the case with online games. Online games, by nature, require upkeep. That is why they often charge by subscription, not by purchase. If you subsribe to a game, it is quite like subscribing to a magazine. If you buy a book, it is quite like buying a game. If you subscribe to a game, you expect moderators to keep the game environment clean, you expect developers to fix bugs, and you expect to be informed when something important affects your game play. When you buy a game, you pay a one-time fee and you don't expect anything to change.
I believe it comes down to whether or not the payment for a game is recurring or one-time purchase only.
