I've sunk a good many hours into this game, on steam and before that release.
This game is no longer the rudimentary block placement simulator it once was, it has changed since its 2001 origins and when I started playing in late 2012.
Let me show you a simple pro-con list, as of the 1.0 update in January 2014:
-Humor, witty dialuogue
-Mashing spacebar has never been more fun
-Kill (metaphors for) all those people in society you dislike, especially Hipsters
-Frequent updates, I can't begin to list all the changes since I started playing
-Holiday Updates especially get better each year. I'm looking forward to a great challenge this easter! :)
-Draco the Archiclaus
-Player moderators are cool and really enjoy muting poor potty mouthed n00bs
-Build everything imaginable with colorful blawks
-Become uber rich and boast about how many times you're gotten carpal tunnel syndrome from grinding the space bar
-TF2-esque hat-collecting simulator
-You actually see the developer ingame
-Small Community means that although it isn't "popular" and the game economy can be slow at times, you really get to know everyone who plays the game, I can say I've made a good many friends through 8bitmmo
-F2P model isn't perfect, you have to buy plat to get all the good goodies. Mystery boxes buyable with earnable gold have at least partially remedied this situation, but it is still hard for the average noob to grab the really great stuff
-The combat sytem has its ups and downs......I'll let you experience this yourself
-Graphics aren't for everyone (but I like 'em :P)
-Game sometimes lacks replayability/"direction". You can find yourself bored if you don't care for building
-Occasional bits of lag, rare and usually not too bad
All in all I rate 8.9/10. I very much expect that other 1.1/10 will be filled with oncoming updates.
It's a great game, everyone should try it.
