It is called common sense. Influence = tourism $$$$. Influence you know the color of your civ. If you play on smaller maps it is easy to hurry up and cover more than half of the map with your influence, since tourism is tied to how much influence you have. It is easy to get a ton of tourism $$$ early in the game. On gigantic or immense it is much harder to got tourism $$$$.
I'm losing patience with you now. I'm not even sure I agree with your point that it doesnt need addressed on ALL map sizes, as Im not sure I want the AI to have all that excessive tourism money on larger maps while theyre huge and I'm tiny, and even so, you're completely missing the point of the issue, and have been told so time and time again by handfuls of posters in this thread. A larger map simply means it'll delay the windfall til about midgame when you'll get even more money because of more influence, and frankly, very few people actually want to play gigantic or immense maps on a regular basis, especially during beta testing when we need quick games.
It's something that's out of whack right now, and needs addressed, unless your point is the devs should simply remove any maps smaller than
Gigantic from the game so no one experiences this...in which case you're a very silly person.
Why are you defending a Beta so vehemently? This is the whole point of beta to feedback on issues like this. Do you
want a broken game, or a game that only works on a certain map size? There are many more ways to boost player economy in the game that would actually add to gameplay, other than the currently ridiculous rate of free tourism money, which adds nothing, and takes away skill and infrastructure significance.
I don't think people really needed any incentives to build influence, as 1)It wins you the game, 2)Gets you free planets/defends yours culturally, and 3)is The unavoidable byproduct of succesful conquest anyway. I personally would like my starting purse back, and a reason to build more than a couple early game antiwar tradeships, a reason to research the trade tree, AI that doesnt gimp itself by wasting reasearch time on trade, and maybe a reason to actually care about maintaining a traderoute.
