The lack of Sandbox MMO games

I’ve been playing MMOs since 1999, some were theme park and some were hybrids or pure sandbox. However, due to the static game mechanics we see these days in theme parks, I barely play any MMOs for more than one week. Some will tell me to play EVE Online, but the thing is, i played it for five years and I can’t do it anymore. I’ve also had fun in Darkfall until the developers managed to completely destroy their product (servers are quite empty these days), so that has left me with a few indie MMOs, that barely can be called BETA games.
