If you think of the PC games coming out this year total, all of them, are you saying you couldn't imagine Elemental being one of the 10 best selling PC games of the year?
It is possible but it wouldn't be one of the games that comes to mind when I think 'what games are likely to be big sellers this year'. I'm still interested in getting it myself, but I just perceive (rightly or wrongly) it as a bit more of a niche game compared to say a more mass market type one such as sins of a solar empire. Having said that,
PC Gamer listed Elemental as one of the 10 most anticipated games of 2010. Now, I'm pretty biased mind you but people do seem to be pretty excited for Elemental.
Looks like I may well have been wrong about the above, so I take it back! I'm impressed (and surprised) Elemental has such anticipation, and although I didn't think it would have been close to civilization in terms of anticipation, evidently it is. I still think it'll struggle to reach the same sales as a civilization game, or one of the other 'big hitters' (such as starcraft, C&C, etc.), but if it is able to obtain/maintain a high level of awarness it might well do it (since I expect it highly likely for it to get a good critical reception).
(back to the OP) It is nice seeing plenty of PC exclusives though. I got a 360 a while ago but I've barely played on it because most of the games I enjoy are strategy - as such the PC has looked like it's getting stronger not weaker these last few years, although I am starting to get worried by strategy games being developed for the console as well (meaning they get dumbed down for the PC). Hopefully it'll only happen in a few cases though.
