once you meet an AI, set slider to 0 and give all GPT to the AI, then set science back to 100%. If you don't build a temple, you are in single NPT.
As I understand it, that is the textbook definition of double-negative GPT, whether you build a temple or not. You are creating money out of thin air.
Here is the rule from the HOF:
"When engaged in negative GPT, you may not have an active deal (nor make one) with any AI involving your gold, lumps sums or GPT. "
Which is exactly what happens once you set the slider back to 100% science.
I think that's probably wrong - on any level but chieftain, you start losing buildings.
According to the rules, it seems to be wrong on all levels.
Of course, on chieftain, there's no penalty at all, so maybe it shouldn't count. I sort of assume the impact of this is small and [...]
The fact that there's no penalty on Chieftain makes it even more abusable! To use this "trick" and make money out of thin air, you need to avoid having buildings on higher difficulty level while on Chieftain, you can do it even if you have buildings.
I havn't really tried it but it seems to me you could basically double your commerce intake on Chieftain with this trick by running max gold, trading it away in GPT deals and then running 100% science and getting your money (that didn't exist) back by selling your techs. Being on chieftain, you would get no penalty at all. You probably would have to time it so that the AIs don't spend all the money or something but I think that's controllable.
Seems like a pretty big abuse if it works this way.
I'm not sure he actually did this, but it does make for an interesting question. So, HOF moderators... is this legal?
All in all, I'm finding his whole post quite fishy.
He gives a list of tips, most of them extremely basic, two of which don't actually work (one is the re-revolution trick and the other one being "use gold to help the FP city build courthouse and market, then start FP at once.", as you will not be able to switch to FP if you use gold to help the city) and one "advice" which is against the HOF rules and seems to have been followed, according to the build dates.
It's quite obvious that English isn't his native language. Well that may explain some confusion, I still don't understand how you can end up giving advice that doesn't actually work in-game.
