I love Minecraft. From time to time when there's a big upgrade, I do a lan party with my brother, his gf and my gf. We build something epic, explore and work together to survive and make our life better. Everyone does what they feel like and you really get a feeling of achievement.
Mojang is TERRIBLE at supporting the game. There are mods out there that literally have hundreds of new things, and they're all balanced and solid. It's inexcusable really.
