Could not beleive when I saw this for sale on here. Haven't played it since the original Xbox. In those days I would play it for hours on end. Firstly, it's not an RPG, it's a hack and slash with D&D elements in it, but the gameplay is so very satisfying, with some amazing music and incredible sound design to back it up. And even at a modern resolution, the graphics still hold up. Could almost be an indie game developed in the last few years. Such a fun game to just kick back, controller in hand, and feel like a badass. Thank you GOG!
The short: It's System Shock 3. The long: This is as close to perfect as any game I can remember playing. It oozes atmosphere, rewards the player for being creative and exploring, and forces you to make decisions in how you play the game that actually matter. It's scary in all the right ways, and when you're creeping through the station, not trusting anything in a room, you'll know you're playing something special. Every aspect of this game has been made with the utmost care, from the level design, to the weapons, the upgrades and the crafting system, the sound, and overall level of polish. It's a masterpiece. Oh and Mick Gordon did the soundtrack. Buy it.
To put it simply, you owe it to yourself to get Terraria. It has attractive, simple graphics, great combat, amazing exploration, depth that you never thought possible, the controls are spot on, and it has unlimited building potential. You will find it very easy to spend a lot of hours in Terraria. Get it. It's worth any price.
