I might. But only if Interplay isn't publishing it. Let's face it, their impatience and incomeptence killed SFC1 and 2 with pretty much everyone but the hard-core trek and SFB fans. (Which is still a sizable fanbase granted, but still...) I already gave my reasons as to why I passed up SFC3. That being said, I think a "Babylon 5 Command" game would definitely be something I'd try out. The thought of getting behind the wheel of an EA Warlock-class warship makes me smile.
Of course the developers of such a game would have to take license on the capabilities of all the races. If the fleets in the game were EXACTLY like the fleets on the show, there would be no point in playing anyone. Of all the major races of B5-namely the EA, Narn, Centauri, Minbari, Shadows, and Vorlons-only the Shadows and the Vorlons were on fairly equal ground. The other four were no match for each other whatsoever. The Narn would be everyone's bi*ch. The Minbari would be able to kick everyone's ass almost without effort.
