I adore Terraria. It's a game that I only started playing in the last couple months because Olli forced me to but it's utterly addictive and so much fun to play. It's not as expansive as Minecraft and doesn't have quite as much to do (depending on how imaginative you are) but I prefer Terraria by a long shot. It's one of those games that once you start you just can't stop haha. Though with uni and such getting in the way I was kind of forced to - I never even managed to clear the corruption </3
If anyone wants to try it out I'd love to!
