So far (through use of a second Op2 window open to get a 'fake' player in) I've had fun completing To The Skies Or To The Grave, Forsaken World and Caught in the Crossfire. They're rather like the Spaceship colony missions with less emphasis on combat and more on fending off disasters. Even Dooms Day was amusing, though I wish the disasters ramped up to catastrophic over time instead of near instantly so you have a chance to struggle onwards against increasing chaos until you eventually collapse.
Not that I mind the combat either. The Spaceship colony missions where Plymouth and Eden have an opposing base on the map were quite fun. So, Caught in the Crossfire was extra fun.
Are there any other (mostly finished and uncrashy) maps like that which aren't already included in the OPU package? From a little Googling and poking around the forum I don't see a lot of survival style maps have been made. Or many maps at all. From what I gather the game isn't very approachable from a custom content perspective, so that is understandable. Though I suspect several Outpost 2 related websites have been buried by the sands of time...
Anyway, thanks for the warm welcome. As much as I'd like to play Op2 online, I pretty much spent a lifetime's worth of gaming with StarCraft back in 2000-2004 for hours every day. Thanks to increasing responsibilities and time constraints as I've gotten older, I don't have free time of any practical quantity to invest in that now.
Had I known there was a community for this game playing it online back then I would of joined in, but I sadly didn't come across this site or the updated Outpost 2 engine until a couple years back, long after my thirst for RTS conquest was satisfied. It's a shame, too; reading around I see you guys try to get fair games going and negotiate rules, team up players to try to balance skill levels etc. in advance, which is exactly the type of folks I'd like to play with. Few games enjoy the balance that StarCraft did -- after a few dozen patches -- and while idealistically the developer would take care of it, it's nice to see players that enjoy a game enough to pick up the slack.
