This modpack was design for roleplay lovers, who want to have fun with some mods.
Mods like Chisel and Chisel and Bits allow you to make amazing cities and houses. You can then bring your city to life with NPCs from CustomNPCs. You can also discover new mods from Mo'Creatures and transform into them to mess with your friends.
I personally run this on 2560m of ram, so I would suggest this amount or more for the game to run more smoothly. I would also suggest adding optifine to help with fps.
