Boundless is a phenomenal building, exploration, and economy game that I'm surprised to have only recently discovered!
It makes many improvements over other voxel building games (e.g., Minecraft, Trove, 7days2die) such as chiseling, which is used to shape boring cubes into interesting shapes such as traingles, slopes, and lattices. And most blocks come in 255 different colors-- which can be very fun to collect!

What truly sets this game apart is the player-driven economy. I spent my first day of gameplay exploring the portal networks, which are used to hop between worlds, while writing down the location of my favorite player shops. My second day was spent buying and selling between shops, flipping goods for profit! Within my first few hours, I made a tidy 30k profit from simply buying and selling raw meat. That was enough coin to afford a full set of decent tools and machines.

I'm now 74 hours in with a maxed out miner and a crafter. My next character/skillset will be a hunter (which allows going on "hunts" used to collect rare materials to sustain portals between worlds). Now that I have plenty of coin, I'm about to begin my first major construction project, and look forward to having a shop of my own some day.

There's some negativity on Steam and the forums which I personally don't understand. The game seems plenty active to me-- 50 concurrent players seems to be more than enough to sustain a working economy and group-based events called hunts. And folks seem friendly and helpful. The developer doesn't appear to be making any new improvements to the game. I'm not mad about that. Maybe I'm an outlier, but I actually prefer infrequent updates to finished games-- few updates means that players can build their worlds and even mod the game (mods are limited to UI improvements, afaik) without worrying that some change will disrupt what they've worked so hard to obtain.

Loving this game so far.
