Christ. Lord Tony and Zeblote. Zeblote? I respect you because you make some pretty amazing add-ons. But seriously? Not everyone who plays Blockland exists solely to play video games. I have a Mac because I am primarily a musician and I use DAWs which are simply better on Mac and for other reasons that I'm not going into.
I'm also a student living in a dorm and don't have the time, space, money, or good enough reason to get a good desktop SPECIFICALLY to run Blockland.
I play mostly only on one server with a password nowadays, and sometimes we use some pretty huge builds. Using the "off" feature is really handy to me most of the time.
