After playing for nearly 40hours in past a week. i have some comparison to make.
Minecraft - i was already bored of mc. i've spent over 3000+ hours on this game, mostly soloing in the survival mode or building a whole town alone. i also played multiplayer with brenda + 25 other people in the crew, i sucked at pvp, looting.
it was annoying to farm and mine was alright, but comparing to terraria, u have 0 idea where u are going, harder to find resources, harder to find dungeons and u gotta put torches every 5 blocks apart. etc etc i can go on for days.

Terraria - when i first saw this game on the app store. i was like, i aint ever gonna buy this game. cause people say it's like mc, but it was 2d.
i've decided to download it after being #10 in app store for like almost a year i guess.
it was little difficult at the beginning, but now i am in to it. it's like the combination of mini-runescape and minecraft.
i love everything about it lol. all kinds of biomes, many dungeons, visible map, character keeps everything, reasonably easy monsters and bosses, enchanting items.
i also gotta give a huge credit to the terraria wikipedia. very very well done. when i am stuck and don't know what to do next, i go to wiki and set goals.
so far so great.

@iBubbles, people in graal do plays mc, terraria <no offense, mostly 10-15 yr olds. //people at my age 15-20 yr olds, plays CS, Destiny, CoD, BF, LoL and other games.

i will personally recommend u: night's edge, hellstone boomerang and minishark <have all 3 together.

and i rekt the whole jungle and summoned queen bee using abeemination for 1 hour. i got tons of bee grenade. i used them on Eye of Chutulu and Brain of Chutulu, they were each rekt in 15 sec.

i topped all of my gears, even little things like accessories, mounts, pets all top class for pre-hardmode, but i am afraid to move on to the hardmode lol.
maybe i will do that on my secondary world. i love all of my creation on the first world.
