Hi, iHaku! Welcome to the Boundless community.
When you begin Boundless, you go through a short tutorial section where you complete objectives that give small bits of experience / coin (our currency). At the very beginning, you spawn in a sanctuary area of sorts called the, ‘Sanctum’. You are then given a tool called a, ‘Totem’ and a, ‘Warp Augment’ that you combine with the Totem. You will then point the Totem at any area on the starting planet of your region (it will be floating in space above you). You can choose to spawn anywhere. There are little stars denoting cities, so you don’t have to spawn near one. Once you make your decision, you’ll complete a portal with a, ‘Warp Conduit’ block provided for you, and spawn where you marked on the map!
I will always say that the two best things about Boundless are: the developers are in constant communication with the players here on the forum, and Boundless doesn’t try to be like Minecraft, despite being in the same genre. These are two wonderful things that greatly set this game apart and will absolutely lead to the game thriving.
To answer your second question: Guilds and PvP will be here in the future, but there is no current work on those aspects that we are aware of. I don’t believe they will ever allow players to raid our homes and kill us / loot our things. You can protect land in Boundless with a Beacon, add/remove plots to change how much land is protected, and once it is protected, other players cannot steal from you. When PvP is added, I believe I’ve heard talk about there being specific planets that are PvP enabled. We’ll know more about that some day, but I truly don’t believe it will be anything like Factions Minecraft on any normal world.
A single player cannot learn all skills, even at max level (Level 50, 1,500 skill points currently). However, each account can create up to three characters to focus on different aspects of the game, so if you truly want to play enough, one person can have all of the essential skills over multiple different characters. (I currently have a gatherer build [mining, digging, et cetera…], a hunter build, and a crafter/builder build.) The reason for this is the developers want to encourage players to interact with each other, and build an economy together. It’s not necessary, but it’s a big help if you don’t want to grind multiple characters to be able to do everything in the game. (I enjoy the game enough that it was worth it to me. )
To reiterate - you don’t need to interact with other players and the economy to enjoy a lot of base aspects of the game. It’s more end-game things there, so you don’t have to worry so much about that.
As you level, you gain plots. Plots are 8x8x8 areas of land that can be claimed. With each set of levels (1-9, 10-19, 20-29, 30-39, 40-50), you gain more plots and skill points to allocate. To initially claim land, you set down a Beacon and fuel it. (basic Beacon Fuel only costs leaves, which can be gathered easily even at the beginning.) Once you have a fueled Beacon, a plot of land in which the Beacon resides will be now yours, and you can use a Beacon Plotter tool to add more plots as you wish. So yes - there is a maximum size of land that one can claim, but that’s proportional to your level. You can also gain more plots past level 50, but no more skill points. Every level you gain past level 50 (which is only shown as level 50+) will give you 10 more plots.
I hope I was able to help, and if you have any more questions, feel free to ask! I’d say this community is rather friendly, and can help you with anything else you might need.
Stay Boundless, my friend!
