I continue to thrash in the throes of Diablo III addiction again. Reaper of Souls has made it a far, far better game than it was at release, and I played it for months on end in it's original state. I've written before about the changes to existing content and systems, which are universally for the better.
The expansion has added another Act to the game, meaning a bunch of new areas, monster types, and bosses to enjoy. It has also added Adventure mode and a few new systems within it--bounties, blood shard gambling, and Nephelam rift raiding. The short of it is that you hunt down specific monsters or due certain events all around the game's world, waypoint by waypoint, and your rewards include blood shards and rift tokens. The shards can be traded to a new NPC for a random piece of gear for the slot of you choosing (I've already gotten a couple of upgrades via this). The rift tokens are consumed by an obelisk to open a portal to a completely randomly generated set of levels where you go to kill monsters until the rift boss drops in, and you kill him as well, for fabulous prizes.
Currently I am working on finishing up a campaign playthrough as my wizard, because before the expansion had come out, I decided to reset quests on that character in order to guarantee a legendary drop on the end boss of the game. I've also got her decked out like never before, with a lot of great new gear, including plenty of legendary and set pieces. I would love to get a complete set to trigger the associated bonuses--so far I have gotten two pair of the same set boots in the last two days. Once I finish up Acts IV and V, I will either concentrate on Adventure mode to further gear the Wizard and Barbarian or start up another character. I'm thinking Demon Hunter, next, to give me one character of each main attribute, Intelligence, Strength, and Dexterity. Why? Why not? Do I go male or female Demon Hunter?
