Okay, I had initial ideas about this. First away: Can the reimagining run into problems with a second attempt who is running in US TV? I think certainly yes. But it doesn´t have to. Does it work in a "today" scenarion? Yes, it does. The TV-Pilot did, why not your game? The ressource-war and consumer-attitude of the aliens is something drop-dead modern and relevant. Now to the ideas at hand. What would such a game need? Get rid of the stuff. 80ies design. Give the Aliens a new spin, so people don´t feel like doing a remake here. But an original game. For ideas I think you can look at a lot of stuff that has recently come out. Half Life 2 (which might be viewed as Post-V pastiche in many ways) jumps to mind. As did Invasion or BSG the Caprica Episodes. The whole Cylons of BSG could be interesting to look at. X-Files, is the mother of Alien conspiracies, obviously. It´s rip-offs had good ideas, too. Once modernized and probably given a few new twists, I am sure the Aliens might work. Only give them some new aspects. Breeding with humans, perhaps? Mindcontrolling stuff? Superior biochemical technology? Clones? Whatever. Sci-Fi has many things in hold. It will give them a fresh feel. When should you start it? Good question. The time of their "adaption" is important, I guess. To lead into the resistance/rebellion and I think we also should have time develop characters, as such a game is about being human, I suppose. It faces the problem, the players are waiting for a well-known reveal. The great old franchise-problem. If not done as a post-franchise, it is always known what will happen next. I have an idea how to avoid that trap and turn it into an advantage even . . . but if you wanna hear these thoughts, maybe better in PM. Or it is ruined before thought through The big question is, do you wanna have an action adventure against an creepy alien invasion or do you prefer a "We both smile at each other, despite knowing you´re really a reptile and I have planted a bomb on your toilet"-scenario. A single thought. You should consider (except you do not like the idea) to move it to another time zone. I know this unpopular with GMs, but have it in the heights of Cold War of before the WWII could lead to an intruiging new spin to things . . .
