I can understand the reluctance to let bad critism hit the forum a day before the official release on the market, but still, there seems to be pleanty of activity in the support forum, with geniune help being given as well as expansions (i.e. fixes) being done on the Day 0 update they'll be launching tomorrow.
The majority of the issues I've seen though has to do with 64-bit systems, which is sad, because I do have a 64-bit OS (Win 7 Ultimate), and have been looking foreward to this game for some time, although I was never able to pre-order it, and its looking slimmer and slimmer that I'll have money to buy it outright retail.
Another thing, though, that has gotten me is the custom map generation. At this point they've admitted that there aren't as many map seeds as what will be released in the Day 0 update, but with the Impulse Reactor there are already dozens of new maps available via mod. Maybe that'll work out, although the bigger map generation for their upcoming 64-bit Version patch suggests there is more in store for that entire system.
I'm still looking forward too it though, and would like to thank everyone here in the forum for the constructive critisms and information. Keep up the good work, and if I can finally get the game, I'll let you all know.
