All my idea is that AEM starts hosting a new server that is modded. There are many mod-packs out there that would be wonderful, for example we could use Infinity from FTB (http://ftbwiki.org/Feed_The_Beast_Infinity) or DireWolf20 (http://ftbwiki.org/Direwolf20_1.7_Pack) but we could also use Technic Packs, either way, a modded server would be a cool expansion I think... Leave any ideas or such in a reply down below ;D
Yea, the only thing about Hexxit is that it is mostly exploration and the map could only be so big. It would run out of things to explore.
