Before any WoW fans pipe in that I shouldn't hate what I haven't played let me point out that I have a level 58 (give or take a level, its been a while) night elf priest on a pvp server. Sure its collecting dust now, but I put alot of hours into the game to get to that point (especially on a pvp server where people seem to love ganking night elves and priests).
So if I've played the game so much, why do I hate it so? Well if your truly interested please just sit right back and you'll hear a tale.
The year was 1994, I was a youngster of not but 11, with a computer running I believe windows 3.1, and a demo in hand for a game that would forever change my life. It was called warcraft and its unique brand of strategy and resource management instantly drew me in. I was quickly hooked and was soon showing the game to all my friends. It took some effort but we even managed to have a multiplayer match. Then 1995 came, with it Windows 95 and a game called Warcraft 2. If warcraft 1 had made me a computer gamer, warcraft 2 officially made me a computer geek. Its combination of witty dialogue, deep strategy, hilarious quotes, and interesting story gave me things I never realized I could get from a game. Truly Warcraft had become a franchise that would hold a special place in my heart always. Years passed, I dabbled in blizzards other offerings, diablo2 was pretty addictive, and starcraft was absolutely brilliant, but it was the new warcraft title I truly hungered for. And then it came, Warcraft 3. It wasn't exactly what I hoped for, I wasn't fond of the 3d graphics, the 2d just looked better to me, but it was more wonderful warcraft humor, strategy, story, and characters.
Then I heard about it. World of Warcraft. It was a project blizzard had started to get in on the cash cow that was the MMORPG. I'd tried my hand at a few MMORPGs over the years but never liked them. They lacked story, interesting characters, and direction beyond "lets gain another level", not to mention they were crazy expensive and had that horrible monthly payment system that makes you feel like your wasting money whenever your not playing. Needless to say I was fearful. To make matters worse I also knew that even though I didn't like MMORPGs, I was a rarity, perhaps a fluke. I'd already lost a few friends to games like ever quest. I didn't want to lose anymore friends. I also knew that because of the monthly fee that these games were ridiculously profitable. If this game was a success they'd have no reason to keep making games, to keep making Warcraft RTS games that I loved so much, no they could just sit on their cash cow, updating it occasionally, and watching the money roll in. And so I secretly wished for its failure, even as they asked me as a long time blizzard supporter to beta test the game for them, which I did.
The beta didn't change my mind on it. It played solidly for a MMORPG sure, but again, I didn't like MMORPGs. Soon the game released and all of my worst fears began to occur one after another. One by one I lost close friends to the game. Every week I'd gather with friends to play card games or do other things but now friends would fail to show up and I'd find out later they were busy playing WoW. Time passed and things only got worse. The game continued to grow in popularity and almost all of my closest friends never wanted to hang out anymore cause they spent all their free time playing WoW. They kept bugging me to play too. Finally my last friend became addicted and as much as I didn't want to play, I really didn't, I also knew that you make concessions for friends. And so I bought the game and played with them.
I won't go into specifics but suffice to say I bored of the game quickly, didn't renew past my free initial month and felt sick for wasting money on buying it. Over several months of barely seeing friends I bought a month hoping this time would be different but still all it did was further my hatred of the game. My last month of play occurred when they gave a free month away due to the release of the expansion. None of it made me feel anything but sick, infact playing on a pvp server so I could play with my friends I actually found playing the game to be rather torturous as I was constantly ganked by high level enemies everywhere I went.
And so we sit here today, 4 years since WoWs release and not a single new Warcraft RTS title. We haven't even gotten a new diablo or starcraft. I did cry tears of joy when I heard starcraft 2 was in production though its release is still unknown. However as much as I'm sure I'll love starcraft 2 with its strategy, story, and all the other things I love about blizzard RTS, it won't bring back the friends I've lost to WoW, nor the time that could have been spent making other quality RTS titles, nor the time and money it forced out of me to get to spend a little time again with my lost friends...
For these reasons, I hate world of warcraft, and wish nothing but bad things upon it.
Incidentally, if its not clear I also generally hate most MMORPGs. The only MMORPG or MMORPG like games I will support are the ones with no monthly fees and preferably have some semblance of story or direction. Games like Guild Wars, Lunia, and even Trickster (though its story is VERY weak atleast its something). Aside from having stories and direction these games don't have monthly fees allowing you to feel ok with say, taking a weekend off to hang with your friends instead of spending it leveling.
Feel free to disagree and explain to me why I'm wrong to hate WoW, or on the off chance anyone agrees with me I'd be happy to learn there are other like minded individuals and why you hate WoW too.
