When referring mass killing of snakes, please use the term serpenticide.
Now, on to the short game vs. long game debate
I am an old crotchety gamer who uses words like crotchety. That being said, I have no problem with 'short' games, provided they give me a complete experience. Of course, it helps that due to wife and child I rarely get a chance to play for much longer than 1 hour at a time. Hence even a short game can take me a while.
I also have no problem with 'long' games, provided they don't drag on without a purpose. Actually, scratch that, I enjoyed Darklands back in the day, and that was a single-player game with NO ending whatsoever. As the men with small penises say, it's not the length that matters, it's how you use it.
Just don't ask me how long I've been working on getting through NWN2...
