The only mod i use is an Inventory editor mod called TooManyItems
i love toomanyitems but i is to stupid to figure out how to install mods =P the directions confuse me, but any way,
Try to make a town with the flat area, i suggest around the mid 1800's because unless you use inventory editors you wont be able to gather 10000000 iron blocks.
.... im gonna need a bigger flat area, i have one clearing thats 50x100(aprox) and one thats 50x50(aprox) soooooo, time to start digging!
btw, i could still use more suggestions for things to build, can never have too many projects lined up =D
I have one. DJ STUDIO! On youtube you can find some videos on custom beat-makers that let you make some awesome songs with note blocks. I'm currently designing one for my server. =D Here's the link to the best tutorial i can find. works on 8-beat, 10-beat, 16-beat, any beat number.
