FYI... Tekkit is the multiplayer variant of the Technic Pack for Minecraft. It includes over 40 mods, mainly industrial mods (Industrial craft, Buildcraft, Redpower and Railcraft) but also has a magical side to it (Equivalent Exchange)and many other mods.
Any Tekkit/Minecraft players out there? We have been playing on a PvP server where you can form factions that attempt to control parts of the world. Its really been a huge improvement in the game.
Its a little complicated once you get started, but really fun. At the beginning, I'm spending most of my time covering my tracks and making sure no one is finding me. I'm hiding chests with supplies in various spots in order to make sure our stuff doesn't get taken.
We're playing with a couple guys from seasonedgamers.com. Pretty cool group of older dudes (non-13 year olds) who like to game with the Timmies if you catch my drift.
