For packaging that is as SC2: WoL and D3 and other Blizzard actually very good, flip top, one has also what provide for the shelf, to the CE, it is not ran, of course, but not a normal plastic bag, which is worth a lot in advance ,
To register: Well is indeed it, battle.net account necessary and you have to be online for multiplayer, updates, achievements, etc. This is at the present time - unfortunately - nothing new, but still annoying, though of course for a game what is aimed at the Multiplayer and eSports and thus be relatively well proceed against cheaters.
What can be a bit annoying, however, if you have the game and then but already there are some patches, if you're unlucky you can then already sitting for a while, but at least there are such powerful patches that with the balance of the MP and Bugs deal of the SP, as Blizzard is already very good, you can hear - partly - on the community.
Campaign: The beautiful décor, the story ok (no spoilers;)) and the performance is also very good (do not play in comparison to other Blizzard, but generally), compared for example to the first part of it falls, however, from what!. As for the layout and principle of campaign missions and the presentation (video, menu, etc.). As for the difficulty, so the campaign was by far easier than SC2: WoL on Brutal I could very quickly collect all the successes here what some long playing times required for WoL.
For Multiplayer: Because everyone has to see whether what is for him to play against real people and not against AI is not something for everyone, otherwise the system is well implemented, latencies almost non-existent, you can now select the Regions (4) where you compete (America is for EU players still ok, Asia / Korea logically then with partially high latencies not always playable). That could be his theoretical account 1 in 4 regions use and pave all with varying degrees of success)
Overall, a very good game, which is not at Part 1 (SC2: WoL) reaches as, but a very good PC game itself is. The rating of 4 stars only refers to the many partially large patches, some of which are not 100% positive / successful story and partially sided / similar missions.
