1. After a while of playing, all saved games show up twice in the list. If I name a save game 'Battle1' for instance, now there will be 2 'Battle1' save games. Only one will load. Of the pair, one has only a time stamp, while the other has the rest of the info, like the campaign map name, etc.. Reloading doesn't make it go away. And when it happens, it happens to *all* saved games. Deleting one of the pair, deletes both, but only if the correct one is selected - if the incorrect one is selected, nothing happens. I use win2k.
2. Web site - I don't have the collector's edition, but the serial number entry on the website to register don't work. It *does* work through SDC, however, so I got the patch just fine. It doesn't have the GC2 in front, and I even tried it on the collector's edition page, it just doesn't work on the web pages. Minor problem since it did work in SDC though. Got the game through gogamer.com
3. A couple times, the next turn button wouldn't appear so I couldn't end my turn. Loading my last saved game solved the problem each time.
4. A few CTD's, but they don't appear to have any rhyme or reason. Sometimes after playin' for a couple hours, sometimes after a few minutes, and never while I'm doin' the same thing as one of the prior times. They're far and few between so they are tolerable, and reloading and continuing on as I was doesn't cause them to happen again, so just a minor annoyance.
