I've seen a lot of games like Neopets come and go, but I think that Neopets has so many features and opportunities for customization (not to mention the LORE of the game has always been top-notch) that it's unique enough to avoid being shut down or going out of business. I'm the only person I know who still plays Neopets, but there seems to be enough die-hard fans all over the world to keep it alive and well. Personally I don't care what issues the site has or how long it takes them to upgrade everything to HTML 5, as long as I don't lose my Zafara baby like I lost my penguin, I'm okay.
