I agree, just bought it yesterday for $30 thanks to a coupon from PC Gamer. Played some of the campagin, and it's definitly Blizzard Quality, maybe better than the orig. I also appreciate the dozens of tweaks that damper tower rushing, make buildings cheaper, and ease the infamous Upkeep cost. All fans of WCIII must get it!
Note that there are already some bug reports, I had initial problems installing the game (numerous corrupt file reports) but I have seen no in-game crashes.
Also there's the price, $34.99. Considering the orig. WCIII was $59.99, this wasn't a huge surpise. I don't know if the game warrants the cost yet but I always expect expansions to be $29.99 or cheaper.
