Yes to gated RR games. I would just love it, (though, tbh my RR isn't that high, had some "accidents" on the way). I also love the idea ATC had about RR being comprised of last X games, or games from last X years.
I myself has never intentionally abandoned a game (except for maybe like my first game here when I didn't know any better). There is no excuse to CD. The game is already ruined? Well, don't ruin it even more for the other players. You have like 1 or 2 SCs and will SURELY die in the couple of next turns? Well, first of all there is nothing sure about the future, and even a 1-2SC nation can have a great impact, that you deprive the game of by CDing. As I mentioned, I have never decided to just leave a game, there was always a reason - blackouts, missing a bus and getting home late for the turn, losing my phone on holidays, and still, if someone looks at my RR and says "well, 90% just won't make it, I don't want to take those chances he'll CD - I don't want him in my game" he has every right to do that, and I hope soon he will have a way to do it as well. Because whatever reasons you try to give to justify you CDing, it just means that for the same reasons you'll CD in the next game, and kids - CDing is bad no matter what.
@ATC, you should take a little break from coding and shoot a public service announcement with puppets and stuff about why CDing is wrong.
