"Absolutely Most FUN game EVER!"5.0 starson by Liberalguy
Pros: FUN FUN FUN, interactive & social, competitive, adventuresome, always changing, great graphics & sound
Cons: addictive, time-consuming, easy to lose track of time because it's so fun, kinda pricey
Summary: By far the game I've played the most. I've played pretty regularly for over 3.5 years - started in Nov 2004 and still enjoy it in June 2008! I used to play daily, and now probably just 5-10 hours per week. When the 2nd expansion comes out, I'll probably be back to 2-3 hours per day.
I like that Blizzard makes all of their games PC/Mac compatible from the beginning. I also like how it gets updated all the time. After years of PVE adventuring, now I mostly enjoy Player-vs-Player. Blizzard developers apparently have good senses of humor as my brother and I are always discovering funny puns and such in names of quests, monsters, npcs, etc.
My brother and I live on opposite coasts, and it's fun to play a game like this together all the time... even though we're in our 30s, it's like we're still 10 years-old playing with toys!
