Johnny , I felt exactly the same ... only until I started playing WoW.
Wait until you experience your first ganking encounter with the horde. Unlike GW where you only interact with other people in outposts - WoW has people ANYWHERE. so while you're in the forest being klapped by a beast - a random person will come by and assist - then run off again (Alliance okes are nice that way
)
This also means that the enemy can attack you at any point in the game - anywhere.
It's really awesome coming across one - then killing him/her - who then call their big buddies to moer you...and you call yours in return. More often than not a single feud or simple fight between two low level characters turns into one huge mob fest.
Here are some points that sold the game to me:
Loading of the game:
There are only really load screens if you do instances (special missions unlike normal quests) and when travelling between continents.
Otherwise you can run through an entire continent without EVER having to wait for that annoying loading/updating/downloading screen GW seems to have every 100m.
Travelling:
Your movement is also much better. You can buy a mount (tiger/horse/whatnot) at lvl40 and an epic mount (orsm tiger/kief horse/ elephant etc.) at lvl 60. Much later on u can get an epic flying mount @ lvl 70. And yes - you can pretty much fly anywhere.
You can also travel by boat to lots of places or fly on a griffin. It's THE most amazing scenery when you fly between places - and since there are no cutscenes you see EVERYTHING all the time. You even see other players riding griffins on the way back past you
Skills:
Unlike GW where each class is human, with WoW you can select just about any race and assign any class to him/her. certain races offer better points to specific classes etc.
Professions:
Aside from being a hunter/warrior/whatnot, you can select 2 main professions. These are completely separate from your fighting skills, for instance:
Mining/skinning/herbalism as gathering skills or tailoring/enchanting/blacksmithing/engineering/leatherworking as a crafting skill. So you can pretty much gather ur own material and make your own armor/weapons/whatnot - or sell it on...
The Auction House:
I spend about 1/4th of my game time here... buying and selling goods at various rates instead of dealing with random outpost lurkers like in GW who trade privately. You can compare prices and either bid on an item or select buyout at a higher rate to secure the item. It works rather well if you need something specific which the vendors don't sell. You can also pick up crazy bargains - which saves you ALOT of time finding it in the field.
Teamwork:
People pay alot for this game and try not to spoil it for each other - i've found (well on the EU servers anyway) ... when you're killing bunnies in a quest and someone else rocks up - they generally leave if u ask nicely instead of competing the whole time. It's also nice to give help and receive it when something is attacking a fellow player - whether you know them or not. It's always nice to have a random priest run past and cast a protective spell on you and then run off.
MMORPG:
In GW you only REALLY deal with other people in outposts or arena. Other than that the game is basically mutliplayer co-op where you and 3 buddies take on the computer's NPC monsters etc. In WoW the NPC's are still there, but there could be a different player friend or foe hiding around each corner.
Payment:
Sure its expensive - but only if you don't play it enough to warrant the subscription fee. If you're not heavy into gaming , dont bother. you'll just end up hating it for taking your money. If you are prepared to spend sufficient time on it, you will not get better value entertainment for that amount of time and money in a month. (unless you know some really cheap scurvey-free hookers) It automatically deducts from your C/C - and if you don't have one or trust the NET with it - you can always buy gaming cards from any pc gaming shop. Scratch the card and enter the key. Hey presto - you're sorted. You can buy more than 1 card instead of going back to the shop every month and just use it when you need to.
Modding:
You can add lots of little side programs which makes the game easier. They're not cheats since theyre Blizzard approved, but they do make things alot easier. i.e.: auctioneer that helps you with pricing (and remembers latest prices etc.), or chartographer which is a better mapping system, or even mods changing your interface so your button layouts are more user friendly. Literally every person's interface looks different.
You can get a free 10 day trial account just to check out the game. Just get the game files from someone and you're set to go. But be warned - you'll be hooked!
) also I am a casual player but I am a senior player amongst a couple of alliances.
