Not sure how much is known about what Meantime was supposed to be like, but judging by what I've read (see: Wikipedia) it doesn't seem worth it to revive the property after 30 years. To be sure, it would be unique, especially in today's market, but time travel? Even the greats fail at making sense of that kind of story, and the current crop at InXile wouldn't have a snowball's chance in hell. That wouldn't be a problem if the game were to be as lulzy as Wasteland (or, say, the Worlds of Ultima games), but I think modern trends dictate otherwise; at the very least I'd expect a different, more self-conscious and self-referential kind of lulzy, less "anything goes, gravitas be damned", more "look at us, we're a regular Monty Python". What's more, players would expect to get to make choices, and in a time travel RPG that's a recipe for disaster if I ever saw one.
