By and by a further

Already Diablo 1 was not a game that could really be called "pure RPG". In a role-playing game, it is probably one of the most fundamental things that you can give a certain personality your character, and that one's decisions are crucial for how accumulating problems are now solved. This is the case, which is probably for some disappointments in expectant friends of role playing the "old school" makes neither in Diablo 1, still in Diablo 2.
Personally, I never felt particularly attracted to RPGs (with a few exceptions such as Knighs of the Old Republic), but am generally more of a friend of first-person shooters and various action games. However, I have both Diablo 1 and Diablo 2 to today much joy.
What I personally (as someone who tends to be more real-time action) find the Diablo games very pleasant, that's very straightforward gameplay. There are no lengthy tutorials, no compulsion to major considerations with regard to the comparison between character / monster values. You start from the beginning by kicking, and gets along very quickly. Monster be combated by simply clicking the left mouse button with the sword / ax / spear / Morgenstern etc., while a click on the right mouse button causes the execution of learned special attacks. It applies, however, attacks, and projectiles such as fireballs, lightning etc. manually, so dodge in real time. This combination between strategic assessment of the opponent or opponents quantities, and thus also ever-present possibility, to have a chance against superior opponents themselves, although is not particularly RPG standard, but also carries a pretty challenging, and ensures that Diablo 2 no play is that ONLY attracts the RPG community, but lovers of almost all genres (including the action-based genres) quite responsive.
Short: In Diablo 1 and 2, both strategic thinking, as well as reflecting ability are in demand. Diablo 2 is neither an RPG, still an action game, even an adventure, but a balanced mix, which may well develop addictive.
Now for the game itself.
In Diablo 2, the player reveals its own little world. We traveled gloomy rainy meadows, catacombs, tombs, caves, deserts, tropical forests ... In Diablo 2, puts its own little world of legends with their own villages, stories, legends and myths. Atmosphere comes at all, because the atmospheric graphic presentation (although only 2D). and the skilful atmospheric background music, adapts expertly to the respective environment. Where you just marched through the hot dusty streets of a forgotten Egyptian-style city where you are attacked by four armed sand robbers and hissing claw vipers, you travel in the next moment in tropical climes, with heavy rainfall, fog-covered swamps, and overgrown jungle passages in which exotic flight monster, and militant indigenous tribes with blowpipes and knives waiting to make a hell. What I mean to say: The environments / monsters / characters are never boring, because for a change is all taken care of.
It's just fun, the game character in this ambient / Monster diversity level up to find (via random generated) magical objects in which you yourself playing time for months always find something new, and all character levels as magicians, Amazon, Barbarian, Paladin etc. by taste.
Diablo 2 is - just like the Diablo 1, which I put EVERY his heart - a really addictive game for both the simplicity behind the game system, and the many variety, making the game a perennial favorite. Part it is the sweaty struggles emanating often scarce, and partly it is the interesting challenging quests, keep a happy. Not infrequently, it is also the desire just to see after "what's coming" what is there to be explored, in which characters are still encountered, and.
My tip is to play in any case, Diablo 2 on Battle.net because only online, Diablo developed its true addictive nature. The single player mode is interesting, but is played out after a few days, and has after the first "gambling through" hard "replayability" character, because a game with flexible plot, Diablo 2 is not. Only if you play Diablo 2 online, you will, in the long time, really have fun with it.
