Sorry if this has been asked before but what is the difference of this 2 versions? the RM33 is the premium paid to get the game 2 days earlier? 

Holy..ss.... Everyone so tense up of getting this game. Relax.... chill.....Does it really make a big different if you play it at 3pm sharp on 15th May or 10pm on 15th May or even 20th May.

Yes, your level will be slightly lower than others, but there are still million of other player playing later than you and is getting even lower level.

For me, just enjoy the game. We had been waiting for almost 10 years since diablo II so, another day or 2 make not much of different
