i would have an ice cave biome, basicly huge ice spheres where you explore, there would be hidden chests in there. or my other idea just for fun: charlie and the chocolate factory biome, rivers of chocolate falling down, dwarfs walking around. would also have mushrooms growing in there etc..
just a small tip, only have minecraft open, dont open skype at the same time. make sure your computer isant overheated. if it is overheated you need to alter your system bits. also try going to start r (run) then type in taskmgr then go to applications 'minecraft' then click view and put priority to high NOT REALTIME! then go to process and put it to high in there. hope this helps
was looking for a server to play on, this site came up and i found it has lots of skins and texture packs on, it also has my favourite thing about this website which is the projects section. it also has a live chat + links to twitch.
