I played the demo of the CE and really enjoyed it. Then I read in the BFG forum that it was a really short game, so I decided to wait for the SE to be released and use a coupon.
I'm going to be a little more selective when it comes to buying CEs from now on because the last 2 I've played, even though they were both wonderful games, were way too short for the $13.99 price tag (3-1/2 hours for the main game and another hour or so for the bonus chapter). I don't really care about the wallpaper, music, screensavers and sketches. I would much rather have a longer game.
