Maybe but no, no and no.
Might be an alternate, but the setting is way too far, Edolas was much closer to it's counterpart.
Those annoying and crude mechanics in those games also suck, big time. They are rookie or early versions, but given that there was already a previous installment, you'd expect it to be more polished by now.
A sandbox force quitting you the game is a problem in fact, it negates the point of the sandbox, and given the small amount of doable things, it wouldn't matter anyway, it's only purpose is to annoy the fuck out of players.
you seem too angry to have a constructive conversation, cool down a bit, take a step back then think about it again :/
settings for an alternative world can be as far as you can imagine them to be, it's not a story that is canon so basicly everything and anything is ok, so while you may be disturbed and annoyed by it, you should keep it it mind or you won't be able to enjoy the game
when a mechanic of a game bother you, why not suggesting an alternative to it either in the thread or by mp ? (then rant about it if the dev don't listen or do something worse ^^)
on the kicked out matter ... you should try any game on a capcom server >< nah seriously, being kicked out of a sandbox after finishing all aivable content when following update state that previous save won't work don't seem like the dev (who is trying to make money out of the game :X) is out to annoy the player (seem like the dumbest move one could make unless it's darck soul ><)
honestly what bother me the most in sandbox game around here is that sometime you spend hours trying everything you can to then learn here that you actualy finished all avaible content and you were actualy just trying to fuck a fly in the ass for art that did not exist T_T so being kicked out is rough and clumsy but actualy better than running in circle for nothing in my book (after you take a step back and cool down because even i personaly felt bothered and angered by it at the beginning :X)
