Diablo III is a hack 'n slash RPG that focuses on loot collection and improving your character. It's set in a world overrun by demons called Sanctuary and only you can stop the demon threat.
Pro Easier to learn and enjoy than most other similar titles
Diablo III is very simple, requiring very little to no planning to succeed. You create a character, pick a skill and just progress through the game while occasionally upgrading your equipment. You can change skills and any stat points you've earned without penalties. You can also choose from one of the 17 difficulty levels, so you can always play at a level that's challenging but not too stressful. All of this creates a game that you can enjoy without worrying about messing up in the long run.
Pro Fun to collect loot
One of the better parts of Diablo III is collecting the piles of gold, the colorful gems, and various pieces of equipment. It's especially exciting when a legendary quality item drops from a monster since it makes a distinct sound effect and shoots a beam of orange/green light into the sky. So whenever a lot of legendary items drop all at once it just feels incredibly satisfying.
Pro Decent selection of character builds to try out
There are more than 50 distinct class/skill combinations, including ranged builds, melee builds, support builds, defensive builds, pure-offense builds, and many more. You're sure to find a build that you'll enjoy playing, whether you prefer to play alone or with friends.
Con Endgame grinding can get really repetitive
The endgame in Diablo III consists of only two things – completing bounties and clearing greater rifts. Both of these have very little variation in them, so quite often you'll run through the same map layouts, clear the same enemies, and complete the same objectives. This gets extremely stale after long play sessions and can cause you not to pick up the game again.
