Believe it or not, people STILL like RTS's. I (and MANY people) have been waiting for Starcraft 2 since beating the first one 10 years ago. Fans have been begging Blizzard for a sequel for ages and after a while it seemed they wouldn't make it; even though we get 2 Warcraft sequels. I'm not sure how Starcraft will be and neither do you. I'm hoping Blizzard DOES bring new things to the table this time around. If the game is good, great, if not then I will say as such. Don't bash fans because of what game they like. Personally, I hate EA games like Madden, NBA Live, etc because I think it's the same crap year after year with just new gimmicks, but some people do like them, and I don't criticize them for doing so. And no, I seriously doubt Yahtzee will hate a game JUST because many other people like it. I have seen ALL his reviews and it's obvious he can think for himself and could care less about what other people think about a game.
Speaking of which of RTS's, they are the only Blizzard games I like, I don't think I could get into WoW and never really got into Diablo. To me RTS's are a break from the typical shoot em up games these days. Speaking of shoot em ups, I now despise Halo, sure it was fun when I played it, but I can't even play it anymore, and I doubt I will be getting anymore Halo games. Additionally, The COD series got VERY old prior to Modern Warfare and I wasn't going to buy anymore COD games if they were only going to be WWII based. COD4 was a godsend and I have no idea why they decided to go BACK to WWII with COD:WAW needless to say I won't get WAW, WWII games are played out and over produced. Blizzard never had a sequel for Starcraft so at least give them a chance to see what they come up with. Like I said if it sucks, I will say as such, but in either case I'm anxious to see the game.
I will however have to check out that Sacrifice game that you mentioned. I'm reading the synopsis now, and seems like an interesting concept.
