Blockland certainly does not fall under the MMORPG category. First of all, it's a sandbox game, yes it includes roleplaying, but it's still a sandbox game, that's what it was intended to be, just like Gmod.Second of all, it's not massive in any way shape or form. The maximum I've ever seen in a server was around 40 people, massive multiplayer games usually are able to hold over 500 people in one server. In theory that is possible in Blockland, but I still wouldn't consider it massive.
Nope, it is a sandbox type of game. It's not those stuffty type of free mmos.
Some of them are good, and some of the ones that cost money suck.
