Talking about Boundless, one MMO that deserves more attention that is progressing nicely and is reaching a point where it's capable to provide one of those unique experiences. Don't get mistaken just by looking at the visuals "Oh look Minecraft", not quite.http://playboundless.com/http://store.steampowered.com/app/324510/
I'll put this review as my words as well: http://steamcommunity.com/profiles/76561198142468145/recommended/324510/
Its unique portals feature is impressive, you can be looking at a portal streaming live from another planet, and another planet is actually another server, from EU/NA East & West and Australia and it simply works seamlessly what is rather impressive in my opinion. The whole thing is fully player-driven, the cities created,
the economy, everything, providing the type of MMO I really like to play, by and for its community, it's based on levels and skill improvement that defines what you can/can't do or how good you are at it with the skill caps (Imagine LIF MMO style on that aspect, but more relaxed), and so on.
This team of developers deserves more support, 2 years ago they had to literally start over by changing the whole thing into a new engine to fix severe problems, today there have been more frequent feature updates that have expanded the game past building, with one economy, trading, PvE combat, with heavy crafting progression while still in Pre-Alpha.
Not sure about you guys, but on a genre where we are constantly being hit with more of the same, this is oxygen for me, and it is been the best I have encountered yet on the MMO/Sandbox sphere.
