Craft the World vs Salem
Craft the World
Craft the World is the game to play if you enjoy the survival, mining, and crafting aspects of Minecraft. The game's quite similar to Minecraft in many ways. You can plant and harvest crops. You can and will actually need to dig to find rare minerals as well. You can also craft a variety of tools, furniture, and, in general, items that will help your dwarves survive the periodic invasions of goblins, the undead, and other otherworldly monsters or will at least make your dwarves content.That said, there are a few very important differences between Craft the World and Minecraft that made the former so unique. Instead of playing a character, you get to become the omnipotent "god" of small dwarves who you can order to do your bidding or you could even control them individually if needed.
The crafting system is quite different too. Don't get me wrong - you still need to combine raw materials to create the stuff you need like in Minecraft, but similar to the crafting system in a standard MMORPG, there's a progression system in place that will allow you to unlock new "technologies" simply by crafting lower-tech items repeatedly...even if you don't really need that many of them. What can you do with the surplus of items then? Well, you can just sell them. There's a shop that sells resources that you may need in exchange for game cash. You can randomly earn game cash by battling creatures and monsters and you could also sell off your extra items for cash.
Craft the World may not be everyone's cup of tea due to the rather repetitive and slightly clumsy crafting system, but the game is still pretty fun and it does offer a challenge for fans of the survival genre.
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.
