At the start of the game, players choose their character class, which are
warrior, sorcerer, and rogue. Each type has their own strengths and weaknesses,
although each class can still use most of the same techniques and weapons. The
RPG setup is very simple; all units have a hit point system, defeating enemies
yields experience points, each level gained gives points to increase stats, and
weapons and armor can be upgraded as the game progresses. The action element
means that battles are not random and enemies will attack the moment they see
the player. It would be nice to have some type of energy bar for the enemy to
see the health, but it's only a minor inconvenience. If players do not want to
go the quest alone, they can team up with a friend over a local network or on
Battle.net. Having teammates not only makes the game more interesting, but can
make for better strategy by having different classes in the same battle.
One aspect of Diablo that may tire players quickly is the constant clicking
of the left mouse button. Basically all games use the left mouse button for
some purpose, but Diablo uses it for virtually every command, action, or
movement in the game. Movement, of course, is the reason players will be doing
most of the mouse clicking. Unlike typical movement keys (i.e. WSAD or arrows),
characters are moved about the map by clicking on the spot where players want
their hero to go, which means that you'll be clicking a whole lot just move
around. This action can get repetitive especially in areas where all the
enemies have been defeated. In addition, attacks can only be performed by
constantly clicking on your opponent, which is random hit and miss chance.
