I have been wondering which Star Trek game to get as well. My collection is lacking one, so naturally it's a void that needs to be filled. I think Frontiers looks like a lot of fun, but the overall largeness of the game has held me back for practical reasons.
Yeah. I feel the same way. I'm in love with the idea of ascendancy and frontiers but feel they may be too big to get to the table much but everything else seems too light (Star Trek panic or 5 year missions)
