Salem vs Trove
Salem
Salem is an old-school and somewhat obscure (but fun) sandbox MMORPG that unlike Wurm Online has a stronger emphasis on its in-depth crafting system and survival aspect rather than building.Similar to Wurm Online though, Salem is not a voxel-based game, but you are still able to mold the game environment through resource gathering, mining and digging in a way that reminds me of the currently-shelved MMORPG, EverQuest Next: Landmark. Of course, although not exactly the focus of the game, you can still build your homestead and the process is quite similar to Wurm Online except that it occurs at a much higher speed.
Not to mention, the game world in Salem is simply humongous to the point where it feels like an actual world. Salem also borrowed some features from ArcheAge where open-world PvP is the norm, so you'll need to be vigilant at all times, but players who kill and steal for no reason will be labelled as criminals and can be punished.
However, as good as it is despite being an indie MMO and all, Salem does have its fair share of flaws due to its low development budget. So, we'd recommend you to take a look at Salem without carrying along any high expectations. It's a pretty good MMORPG like Minecraft, but if you're expecting a Minecraft clone, you may end up disappointing yourself.
Trove
Trove is a voxel-based sandbox MMORPG that is quite similar to the insanely-popular game, Minecraft. Uniquely though, Trove has a lot more of the MMO element rather than Minecraft. You can play as any 1 of the whopping 14 character classes available and venture out into the many different biomes and worlds to search for resources (both common and rare) to gather, dungeons to conquer and randomly-spawned world bosses to defeat. There are even plenty of cool-looking mounts and pets that you can search for and collect.Not to mention, you can have fun turning the stuff you've collected into various tools and weapons via the game's in-depth crafting system too. Or you could simply use these blocks as building materials to construct your own home in allocated spots scattered throughout the game world. Interestingly, the game also allows players to use its sandbox feature to design and build amazing dungeons. All submitted player-made dungeons will then be judged by the developers and a select few will then make it into the actual game world. How amazing it would be to see players trying their darnest to raid a dungeon you've built!
It's a no brainer that if you enjoy Minecraft but find its multiplayer a bit lacking, then you'll love Trove. However, we would definitely recommend this game to anyone who loves voxel-based sandbox games like Roblox and Kogama as well.
