Current games whos names I will not mention *cough minecraft cough* are making everybody think that games get massive amounts of content every update no matter what nowadays.
Those "games" are still in development.
Blockland, however, is the full retail game. Content doesn't need to be added with every update constantly with how many addons we have IMO. Just because a game is updating doesn't mean it will bring with it a stuff ton of cool features that make the game 10000x better.
Hell, it could just be a bugfix update. That's good enough for me.
*sigh*
