Past review: "you can build stuff, so thats cool"
I'd like to elaborate more in this review and touch some key points people are making, being here since 2010 and witnessing it first-hand.
The community is very odd. In-game is mostly friendly with the exception of 1 or 2 people MAYBE per server that are hostile. On a rare occurence, the entire server is filled with them (INCLUDING ADMINS) which is why we use the Drama board on the forums in the first place. Speaking of the forums, the forumer community is different, to say the least. Think if Facepunch and Something Awful had a baby out of wedlock and it grew into a cynical teenager in a few short months. Well, maybe that isn't the fully correct analogy, but keep reading.
The forum community is generally hostile towards certain kinds of people, so it is advised that you generally look around and see how people act and post before doing it yourself. Also, read up on the rules.
Unspoken rules are: No trolling, don't spam emotes/giant text, and a few others I may be forgetting. The forums is completely optional anyways, but it has most of the add-ons the game is made more enjoyable by, so I suggest you only visit: Gamemodes, Add-Ons, Music, Prints/Decals/Faces, and Environment Files.
--The game itself--
The tutorial pretty much tells you what you need to know about the game's basic mechanics, so I'll leave that to you. What it doesn't teach you about is: Macros, Driving (which is very simple), navigating guis (also simple), but those aren't really too big. For ones the tutorial misses, check the controls menu in options.
As for servers and creativity, sadly, there isn't a whole lot. Players don't seem to host great ideas or take a risk because all the people flock to already popular servers, such as Tezuni's Prison Escape or Anthony's Speedkart. Server titles are like the first lines in books. Unless your server is original or grabs the user in, the user won't come. It's simple once you get used to it.
--Updates and the game's future--
Yes, Badspot does work in a team with other people (Rotondo, Kompressor). No, updates and activities aren't frequent. Yes, an update is in the works (Rotondo has confirmed a hat update). No it isn't out yet. These are basically all you need to know, as updates are a very rare occurence. What makes up for this, though, is the amount of user-created content that bends the game to do extraordinary things, such as a full recreation of tr_walkway (BL_Botway), a gamemode about dodging boulders while reaching the top of a hill, a full recreation of Imscared, buildable vehicles (ask around for it), a quake 3 gametype, thousands of custom bricks, weapons, vehicles, and environments, and more. Wow.
Is it a Minecraft/Roblox clone? No. The game came out in 2004 originally (v0002), and retail was released in 2007. Roblox mainly was conceived in 2006/2007, and Minecraft was created in 2009. But none of these games are similar enough to compare unless you take into account that they are all block-games.
Are you guys at war with Roblox/Minecraft? Not at all. We don't even like to assume that is the case, but Roblox takes that very seriously and even mentioning BL on their forums is a ban. A lot of Blockland players are actually active Roblox and Minecraft players, such as myself. To each his own.
Also, maps are not as dead as everyone says they are. A friend of mine named Wrapperup has restored the bedroom using static shapes and is teamed up with other users to recreate past maps such as the Kitchen, Neib's Model House, GSF maps, and more. See it here.
To sum it all up, Blockland is a neat experience with loads of user created content to make up for the lack of updates. It's optional forums are kind of hostile, but the users on the forums are nice if you pick them out from the ♥♥♥♥♥♥♥s. The in-game community is neutral. The game's mechanics are easily explained. Think GMOD with legos.
