Re: old titles on new computers, try using DOS emulators. DOSBox is one I've heard of, but haven't tried. Alternatively, make a DOS startup disk and use that.
Re: iCapn's point, I agree that StarDock has a good reputation. I'd trust them to make a game with fun mechanics and overal gameplay design. As for making sequels, I think it really depends on the nature of the original games. SC3 sucked because...well, for too many reasons to get into here. But one of the primary reasons was because SC2 was heavily based on story and dialogue, and SC3 basically butchered that story a la Highlander 2: the Crappening.
If a game is primarily based on mechanics, like most 4X games are (I mean, let's be honest here. Does it matter if the other races are "Lizard People" or some other type of race?), then as long as a company has a proven record with developing games with good mechanics, I'd trust 'em. If I knew about the original MoM, I might trust StarDock to make a sequel, since it'd probably be MOSTLY based on mechanics.
As far as, for example, a Star Control sequel, I'd trust StarDock to do a good job on their own, especially with mechanics, but would rather hear the original creators' visions as far as story goes. IE: You can like both Tom Clancy and John Grisham as writers, but you wouldn't want John Grisham writing a story about Tom Clancy characters, would you?
That's the only reason I wouldn't pre-order a Star Control sequel -- well, that and because of the somewhat up-in-the-air status of the property itself, legally speaking, which could result in sequels moving further away from the original material that made me like the franchise in the first place. That's the primary reason why I'd want the Toys for Bob guys to at least write the story and dialogue for the sequel to Star Control.
Anyway, as far as MoM goes, i may have to check it out now, if I can get a decent DOS emulator going on my rig.
