I agree with those who say not enough games get absolutely hammered by reviewers for having severe issues on release- no matter what the issues are.
But there's two sides to it. For one there are legitimate issues that really are unpredictable - should a company suffer due to this?
And on top of that there's the fact that historically, games with really bad issues have gotten off scott free regardless. Do you see WoW expansions getting lower reviews due to those first few days after release being total lag/crashfests? Nope.
How many other games have teething problems on release only to be corrected later?
Where do you draw a line with an issue like this?
If anything perhaps yes, Stardock should cop it due to releasing a multiplayer title where the multiplayer basically didnt work....but on the same note, it should also warrant a re-review a week/2 weeks/month later once it's given a reasonable chance to correct the issues. A month is probably too long - perhaps a week maximum.
Demigod is a great game - when or if you get to actually play it. I do not remotely count the skirmish or tournament modes as any form of single player component. Imo just because you can play it offline doesn't mean it's an actual single player portion. A campaign of even the most bare bones implementation is about the limit here imo.
