Diablo III First Impressions & Tips
So far, I've spent a decent chunk of time with the game, although I have not beaten it yet because I'm working on it with a friend. I've got a level 32 Demon Hunter and a level 23 Barbarian. My Demon Hunter is in the midst of completing Act IV, but I wanted to give my first impressions of the game to those of you who were interested. Keep in mind that I haven't played the first two, but I have played loads of RPGs and am sympathetic to the never-ending quest for phat loot. I'll include a few tips and pointers that helped me get on my way.
Combat/Gameplay
Although the game gets off to a bit of a slow start with fairly straightforward mobs, your skill-set expands right before you reach Act II. As a level 1 character, you will have access to only your most basic primary skill. From what I've played around with, the primary attack generates your main resource (hatred for DH, fury for Barbarians, etc).
Shortly after bashing/impaling/zapping some undead creatures, you will level up and unlock your secondary skill. These use your resources, so generally a balance must be found between your primary and secondary attacks.
The skill system is quite intuitive, but I will explain it briefly. As you level up, you will continue to unlock new skills in addition to runes for each of those skills. The runes act as modifiers that alter the skill in ways that might better suit your playstyle or give you the edge over a difficult boss. For example, my Elemental Arrow skill has various runes that change what kind of elemental damage I deal. Only one rune may be active per skill at any time, but I can essentially switch on the fly (there is a short cooldown once you do switch skills/runes).
For each level, new skills and/or runes are unlocked so you always have something new to play with. As I mentioned, the game starts off a bit slowly (perhaps because I ran through the beta a few times), but once the Skeleton King is vanquished, it's off to greener (or, yellow/orange-ish) pastures.
All the while, you will be running your main quests and exploring side-dungeons in search of loot. What you should always be on the lookout for are the elite mobs. There are blue and yellow varieties that will usually drop some decent gear.
The gear tiers are: Inferior<Normal<Superior<Magic<Rare<Legendary
Most white (the first three tiers) gear is not worth picking up except in the early levels where something is better than nothing. However, most of this stuff is trash and won't even fetch you a decent price at the vendor. I always pick up any blue+ items because I can salvage those for crafting materials (more on that later).
*Finally, most gear can be equipped by all classes. There are a few restrictions and some class-specific items (barbarians can't use 2-handed bows, for example).
I can choose any quest to play from (as long as I have completed it on that character) and my friends can join me as long as they have unlocked the difficulty level I am on, and vice versa. All this takes is seeing that a friend is online and clicking the "Quick Join" button. It's quick and painless.
Crafting & Artisans
A lot of people were complaining on the official forums about how crafting hardly yields anything useful. While partly true, I have gotten many useful things from crafting, even if MY CHARACTER cannot use it. Chances are I will be trying other classes or my friend might be due for an upgrade. Additionally, the auction house is another outlet for your unwanted goods.
Again, I haven't been very lucky with what I've gotten out of crafting for my particular character, but because I'm always salvaging useless magic items (the standard, white items are not salvageable), I've been able to keep on trying to craft that pair of chainmail pants I so desperately need to upgrade.
Everytime I upgrade the crafter, I learn a few new recipes but the price can be rather steep. Sometimes you'll craft an item that boosts dexterity, strength, and intelligence... which basically renders the item useless unless the stats are ridiculous. My strategy has been to keep gear I plan on re-using with other characters (items are not bound, so you can use a weapon for a few levels and sell it on the AH when you've outgrown it) and to salvage/AH stuff I don't plan on using again.
*I forgot to mention the jewel artisan. I know there were gems in Diablo 2, and the system in Diablo 3 is fairly straightforward. Gems can be combined to create even better versions. The gems will apply different stat increases based on: what type of gem it is and which slot it's placed into (helm, weapon, other). A gem can only be placed in a piece of armor with sockets in it, so this is also something to look for if you're buying an item off the AH.
It's a pretty simple system and the jeweler can be upgraded just like the crafter.
Conclusion
I know this was a bit disjointed and may be more guide than review, but I hope I've highlighted some of the essential aspects of gameplay to get you enjoying the game.
Overall, I'm really enjoying the game. It can be frustrating if you constantly pick up gear that's useless for your particular class, but with that said, there are some bargains to be found on the AH. Many people might shy away from using the AH because some of the gear you will find there is ridiculously powerful, but ultimately, it's your choice how you plan to use it. I highly recommend spending the money to expand your stash slots so you have more room to store items between all your characters.
Finally, let me know if you guys would like me to cover a particular aspect of the game. I'm sure I've missed a million things but I'm sure someone here who hasn't played it yet will have some questions about an important aspect of gameplay that I've forgotten.
Once I get into the higher difficulty modes, I'll write up my impressions again.
