We're not developing a Civ6 here... I sympathize your ideas about helping a poor fellow AI but this thread is not titled "Making the Game More Enjoyable" either (despite the fact that it will become more enjoyable with all those exploits eliminated). Like it or not, "luxurie-to-lump-sum trading" is the part of Civ5 and its gameplay. So when you propose to ban this feature as the only way to stop the exploits it is OK, but when you insist on the ban (and arising gameplay changes) as just a trick to fix some AI problems (which is the whole big story on its own) that causes quite understandable "resistance". Let me rephase it: Do you really think the poor AI is the most important problem of the HoF?
We're discussing Civ5 here which still has an expansion and a bunch of patches to go, including (hopefully) a HoF mod. This is very much on topic.
It's not about AI, it's about game balance. Of course it's not the only problem. In my opinion, HoF format itself is the biggest problem and that's the reason why it will never be as popular as GotM. People don't want to reroll, don't want to use the same cookie cutter strategies every time, don't want to play 5 levels beyond their skill and yes, don't want to abuse elements of the game they dislike and consider unbalanced. The fact that after all this time despite all the critique the rules haven't been relaxed, speaks for itself. There are many people who don't want them to be relaxed. Therefore it is indeed a problem.
Players recognize that Petra is OP, that DF is OP, that given a civ of your choice Spain is OP and that's ok to speak about nerfing these elements. Lump sums are not different.
Sorry, I don't play war-games. (Besides my style of civ playing may take up to an hour per a turn

)
Well, you don't have to. But if you choose to play SP, AI stays a major factor. By dismissing the necessity to make it better, you're basically saying it's not about Civ, it's doesn't really matter what kind of game you're playing, it's only about competition vs. other humans. And I know you don't mean that.
I was playing devil's advocate regarding RNG. The most basic HoF rule is RNG in a nutshell: only one person is allowed to play a given map. The map I may draw is not the same as the one someone else draws. I would contend that if RNG is to be eliminated then this rule has to go. I am also of the opinion that the HoF has gotten this concept right in a big way. It keeps people playing. Perhaps (devil's advocate speaking) the HoF should require maps to be purchased from the site. If a person wants to play for a fastest conquest slot, he or she could buy a certain quantity of maps (in, say, increments of 100?) for the attempt. The usual disclaimers would apply. e.g No refund for any unused maps, your results may vary, etc.
It's a double edged sword as it keeps some playing and stops others from playing.

I think you got me wrong. I have no problem with RNG and was not suggesting it should be gone. But I also don't fool myself by thinking that playing field is level. Assuming the same skill of two players, the one with more time and willingness to reroll will win. And since none of us can reroll infinitely and each competition is based on a single game rather than a series of multiple games, there is no long run.
you and Pilgrim try to force your role - playing fantasies on everyone else.
Lol. You don't even believe in that yourself.
If lump sum deals will be banned, i'll quit, that's all i'm saying.
Or adjust. People were saying courthouse bug is not a bug, but a feature, since it hasn't been patched. It was patched eventually and people get adjusted. RA's and GS were nerfed, slingshots were nerfed and the list is very long. Things get balanced up all the time and we all adjust.
Ribannah, (who had won GOTM gold few times) would disagree with you. She didn't use gold exploits (and many other exploits) and still beaten everyone, including tommynt. So it's not impossible. Yet needs a hell of a brain

.
Hasn't she quit GotM due to the increasing popularity of a certain play style which she thought was not consistent with the spirit of fair play and the vastly growing community that's parroting this style? Was she attempting to enforce her role-playing fantasies too?
I know that trying to explain this to tommynt is pointless, his competitiveness is so high and the ego is so bloated, he doesn't care about the process. But apart from him and maybe few of his loyal followers, the vast majority of players do care about the process and refuse to sacrifice it in favor of tommynt and alike. You never stroked me as such player. What do I know...
