Diablo III Ultimate Evil Edition
Reaper of Souls is the expansion pack for Diablo 3; and it's more than just an expansion pack. When it was first announced, I'd already been playing Diablo 3 for some time and was expecting to be able to just download a patch for my existing game.
New bonuses during gameplay; great new class; new challenges for all the characters; new difficulties; cool new merchant; brand new story chapter
Story not as challenging for certain characters; manual return to towns out of story missions; multiple side quests improperly triggering; the new crafting material interferes in treasure drops; co-op players can't share Nephlem Rift opening; no content patches for 360/PS3 owners
