I've been burned so many times the last few years on sequels. Civ3, Moo3, CFS3, B17:TME, SH2......and I should know better given how long I've been playing games on the PC.
If they did one thing right, it was releasing the demo ahead of time. First, it shows they're standing by their work and they believe in it. I admire that. What does it say about a game if you're afraid to release a demo ahead of, or at, shipping time? Second, it made me think about my purchase, instead of blindingly buying it because I liked the first one so much, like in my list above. I should change my nic to "Sucker4hype", but it's easy to get carried away if you enjoyed a prior title a great deal.
So I await further reviews. Based on what I've read so far, despite the scores, I remain unconvinced this game is for me.
