so i was looking for upcoming free sandbox mmo and i came across this:Albion Online
basically it is a GvG 5v5 territory war game with player housing and crafting(a true sandbox by my opinion) so if you like LoL and dont want to wait for games to load or want to craft until you are master of crafting or making a mansion for yourself you can do that with the classless character you will have. play it on the go with Android or IOS or play it on any desktop or laptop. but it is in Alpha right now.
if any more info you need go to www.albiononline.com
