A massively fun game. You have no main goal, but killing all of the bosses seems like the most realistic one. And, oh my, does this game have a lot of memorable ones. For the sake of not spoiling anything, I won't say any of them, but most of them are completely unique, and even those that aren't, still have at least something new and fresh to bring. But one of the major gripes I have with the game, is how much the progression gets tied to the bosses, especially in Hardmode. A few other activities would've been greatly appreciated. Terraria does something I haven't seen a game do, and that is the prospect of characters and worlds being two different things. What I mean by that, is that when you create a world, any of your characters can visit it. Yes, this does mean your high-levelled character can give your three-minute-old one an absolutely over-powered sword, but seeming as the player has already acquired the item, it does little to no harm. The items are all incredibly unique, and I was acquiring them by the bushel, items such as the Umbrella, or the Money Through. There is usually a wacky event happening for you to partake in. Another major part of the game is house-building. While making a house early-game is quite a fun task, later it becomes laborious work, and houses that fit the criteria always have a chance to not work at all. Graphically, the game looks great. Every locale, NPC and block is well-made, and I enjoy the simplistic style. The music in the game is also a high note, no pun intended. From the main theme, to the ominous one of the Corruption, each track fits where you are well, and they transition oh-so perfectly. Mods are another giant factor of Terraria and there's no shortage of them. Small, yet almost compulsory ones, such as the Boss Checklist are just as great as massive, content-rich expansions that mods like Thorium give you. Co-op is just as you'd think it'd be, and it is quite enjoyable. Overall, Terraria is a very enjoyable game. Except for the second half not being as enjoyable as the first, and a couple other redundant features that I dislike, the game is a flawless 2D action-adventure game, with heavy RPG elements.
