THIS IS A JOKE, SO DON'T GET ALL PISSED!!!
Here are my theories of how Starcraft II could fail (If you're a Blizzard fan boy, then you're likely to get pissed anyway):
Everyone spends a week camped outside the game store to get their hands on a copy of Starcraft II. Everyone gets it, and some problems come up:
1) The game uses intrusive DRM. People get pissed. "You Blizzard people should have known better!" kind of protests. Game gets posted on torrent sites, becomes the most torrented game in history, beating even Spore.
2) Gamestop releases the game early. People flood in and buy it. Preorder people feel like they've been screwed. Loads of people try to play online, but the servers aren't ready. People and reviewers get pissed. (Yes, this is what happened to Demigod)
3) Starcraft fans and worshippers get game. They play it. They feel like Blizzard has altered too much stuff in the game. They get pissed. They say game sucks, and potential players avoid the game.
4) Starcraft fans and worshippers get game. The play it. They feel like Blizzard didn't add enough new stuff to the game. They get pissed. They call Starcraft II things like disappointing, carbon copy with better graphics (graphic still won't blow anyone away, based on what I've seen), and stuff like that. They say game sucks, and potential players avoid the game.
5) Person who has either never heard of Starcraft II, or heard about it but hasn't played it (this situation would be after release, if that day ever comes). Person either buys game or plays a demo. Player thinks, "This game is like pretty much every other RTS out there! Three sides, breakneck pace, typical base building, and the other ingredients in an generic RTS!" Player stops playing. Alternatively, Player gets Starcraft II, goes online, and joins a match. There he gets his butt handed to him by a Korean Starcraft devotee. In either case, Player gets pissed and stops playing
6) (This will never happen, but it would SUCK for Blizzard!) All the Korean fans of Starcraft drool in anticipation of Starcraft II. They then learn that the South Korean government has banned Starcraft II for some reason, say, a hidden reference to the conflict between North and South Korea. Every single person in Korea gets pissed (Starcraft is the national pastime there). Riots start, on the street and the Internet (regular Koreans on the street, lazy Blizzard obsessed Koreans too fat to get out of their chairs on the internet). I don't wanna describe that mess anymore.
These are six theories. (Hopefully you'll find them funny). If you made up a new one, feel free to post it! Don't flood the thread with new theories, though.
