Minecraft is just a superior game and deserves more credit :)
I remember seeing a person play this and it is pretty funn.
As of 1.9 in minecraft Terraria will be FAR better than minecraft. Terraria has more variety and takes more skill while minecraft now has a cooldown on attacking and has alot less options unless you are into commands and pluggins. AKA with both being vanilla terraria is best but terraria has much less "mod" potential unlike minecraft with it's easy to learn command base and being a very java script related game (easy to program) the bad thing is that minecraft has many more hackers. But they are not as destructive as hackers in terraria.
I would say that both Terraria and Minecraft are good, but Terraria has some more qualities that make it more interesting. In Minecraft, the point of survival mode is to survive, craft, explore, fight, and build. It gets pretty boring after awhile, with nothing do do except farm, craft and fight every day. If you have a mod, it can spice it up, but normal is pretty boring. That is why I only play on servers now, which provide a variety of games and challenges. In Terraria, there are an unlimited amount of challenges and places to explore. There is always something new to explore or fight. In Minecraft, there is the normal mobs, and afew bosses, including the enderdragon and wither. Terraria has so many bosses it's hard to count them. There's the Eye of Cuthulu, Eater of Worlds, Brain of Cuthulu, Skeletron, King Slime, Dungeon guardian, Wall of Flesh, Wyvern, Duke Fishron, Moon Lord, The Twins, Skeletron Prime, and so many others. In Terraria, you can also build and create beautiful homes, buildings, etc. just like you can do in Minecraft. There is definitely way more to explore in Terraria, and many more elements to the game. That is why I think Terraria is slightly better than Minecraft.
