I liked it, I am content that I bought it and finished it. Will you like it? It is rather small and simple game. If you played already games from this genre you won't see anything new but you will see some old stuff done very well. I had some problem with running it but GOG Support manage to help me and I finished the game without any more troubles.
Great original game with lot of content: enemies, bosses, mobs, bioms, NPCs, armors, weapons, magic, potions, tresures and blocks to build with. I was one of the people who thought that this is just a 2D Minecraft clone. Only after I played I realize that Terraria has it own story, own gimmics and own ideas for itself. This game earned all of the hype it gets!
