Regarding ratings, I can absolutely see an argument for allowing the complete game outcome after replacement with a bot count. Currently, the bot is very likely to buy Provinces/points when able pushing the game to a conclusion. It's not unreasonable to expect far behind players in multiplayer games to do this to speed things along, too. Would ignoring the final outcome of games with resignations that are finished with a bot give better rankings than not counting it? I don't think that's an obvious "yes", at all.The idea isn't to do the best job of ranking the players in this situation; it's to make the players the happiest they can be.
I think the players should have the option to continue the game with a bot player, or to maybe start the game over as a 2P game in this case. Give them all the options, I don't think anyone disagrees on that.
After reading your posts, though, I'm actually unclear now on what your stance is with regard to the leaderboard. I think everyone agrees that the guy who resigned should lose his matchups against the other two players who didn't resign, but what about the matchup between the two remaining players? What leaderboard result should be recorded for that matchup? Some options I've seen suggested are:
1. The matchup is completely discarded (this is what I think should happen)
2. The matchup is counted as a draw
3. A game with a bot will determine the result of the matchup, with the bot's score/placement ignored
4. Same as (3), only the bot passes all of its turns and never buys/gains/plays anything
5. A new 2P game with the same kingdom is started and the result from that is used.
6. Players will have the option of continuing the game with a bot or (5). If they all choose the bot option, then (3) or (4). If there is no agreement, then (1) or (2). (or maybe only some of these options are presented to the players)
...Or maybe some variation on these.
I'm only talking about what the leaderboard shows for rated games, hopefully what I'm saying makes sense. I'm beginning to think that what's being discussed here is what players should do after someone resigns, independent of what is recorded on the leaderboard, which is why I'm asking this.
I remain convinced that to preserve the integrity of the leaderboard, only option (1) is acceptable. With the current bot, any options that involve a bot are pretty clearly awful to me. Granted, there are still bugs in the cards so the integrity of the leaderboard is already gone, but that's not an excuse to do the wrong thing here.
