I saw 6th Basic on DriveThru for the very reasonable price of $15. Hey, that's very reasonable, right? I'm looking forward to getting into it. Nobody in my HERO group has any experience with 6th, and the second group I've started playing with has no HERO experience at all. I'm running a Tail Spin-esque game with Marvel Heroic Roleplaying right now, but they said they'd like to do a supers game after

My search-fu was weak. I tried with Google and Bing, and couldn't find specifics

Right now I'm pondering the differences between the two. I've got 5th Revised and Sidekick, so I'm familiar with the idea that one is everything and a bag of chips, while the other one is streamline and missing a fair bit of stuff. But what I'm not sure of is how much stuff is Basic missing, and what stuff specifically? I find that I don't use most of the rules in the full version of 5th, so I don't know if 6th would be any different. Also, after 5+ years since 6th's release, how is it? First impressions are great and all, but I'm more curious about the "long haul" perspective.
