411mania - If Castlevania and Minecraft had a 16-bit lovechild it would be Terraria. With its mix of exploration, resource gathering, boss battling and crafting, there is something here for gamers of just about any taste.
With a charming retro sprite aesthetic and an upbeat chiptune soundtrack, the randomly generated world will suck you in for hours. Making it portable has only made it more addictive.
One small issue is the amount of time that must be put into the game to get anywhere. It took me a good 20 hours just to attempt the first boss with any hope of succeeding (I tried earlier and failed miserably).
