So from what I heard that most people doesn't like "change", and I can tell you now this isn't like minecraft, terraria and runescape at all. MS2 plays very very very very different. It still sticks with only keyboard gameplay just like MS, also the I amount of potions that you have to spam is still there. Also MS2 just applies modern MMORPGs do right now such as housing and public events which 30 - 50 players can join in 1 channel to defeat a "world boss" monster just like GW2 did. Cool thing about the housing is that they have rents and space that you can buy which is pretty neat and anyone can visit it I believe. I am just basing it on my experience on playing KMS2 and I didn't get too far to the point of raids and party quests.
Anyway the reason why people are saying that it is a copy of some games because of how the game looks AKA box = minecraft. Trust me nowhere close to minecraft expect box spaced lands that's pretty much it. Nowhere close to terraria and runescape at all even.
