Wonderful game to play if you just want to relax. Personally, I sink around ~100-150 into every single playthrough, because I am a completionist. Setting yourself goals at the start of a new game, is really great. It gives you a sense of progress and satisfaction when you hit just one of these goals.

I can't really review the game from at multiplayer stand-point, as I don't really enjoy nor have I really played it. I don't like multiplayer in Terraria, and I don't like it because you also have to gather materials for the second, third, fourth, fifth or however many people you're playing with. It just gets tedious.
