What Is Your Favorite Way To Screw-Over The AI Races?

Support the Korath, ally with same, then cackle gleefully while they spore the shit out of everyone and you buy the newly invaded 0 pop planets for pocket change.

Buying newly colonized low pop planets for nothing but influence.

Buying everyone's asteroid miners with influence to use them as free scouts.

Paying one civ to attack another as soon as you meet them, interrrupting both civs' colony rush.

Feed them with as much technologies (for Money, Ships, Planets, etc) as possible while always keeping ahead slightly with the essential(s).

Declare galaxy wide war(s) and invade everything that remains except for the 74.5% Influence victory gap.

Exploits or not, my strategy or tactical decisions are probably never as good or efficient as whatever Ethical choice made when it matters most.

Well, I might have given someone Industrial Sectors or something else expensive to build right before a war with them 'happened.' The AIs don't seem to know how to say no to untimely upgrades.

If you give the AI weapons technology that surpasses their own, they will adopt it.  If you have the defenses for that technology and they don't...

Research all the Influence techs early, along with the Diplomacy techs. Buy all their BC in exchange for influence so they don't have money to rush buy things with. Having no cash the AI will build attackless and defenseless hulls in hopes of upgrading later. Just before declaring war, buy off all their ships you can weither they have weapons or not, and upgrade those that don't. -Perferably using influence instead of cash. Then declare war and laugh as the AI doesn't have any ships to defend against the invasion.

If you want to be really evil, sell/give the AI a higher-level tech in production, moral, and/or research so all their planets will be concentrated on social production. You're almost assured of no retaliation as you send in the transports to take over.

Ohhh, I'm gonna try that!

Pay the Dregin to go to war with tech or ships, let their SA go off, creating more ships for them to maintain...rinse/repeat until their economy is tanked.  Combine with sabotaging their econ buildings to further bottleneck their economy, since now theyare also spending on spies....Want to see a superpower go broke and collapse upon itself?

Wow you exploiting lil bassturds. Never seen so much ai exploiting in all my born days. Truely proves the Game Genie age has arrived. In case you don't know what a game Genie is it was a console cheat mechanism invented back in the mid 80's to allow kids to cheat their way through games and teach them to exploit the mechanics of the game instead of trying to beat it on their own. Then when PC's arrived game magazines started publishing cheat codes and I was just amazed game developers were leaving them in the games. Cheating and exploiting has arrived it's a sad day for gaming.

Just out of curiosity, what is the highest difficulty level you have played so far?

LOL!  I assume you prefer checkers to chess, too.  We should get together for a poker game or two.    

Tough. I go for broke and call their bluffs on cash figures rather than odds against.

This way, my brain can still evaluate instead of suffering from weird Mega conditionned Events.

Poker? Naaaa, too easy. Although i tried managing Black-Jack & Roulette tables in pre-training fast track for the Casino of Montreal in summer 93 -- but, as it happens, turnover was much lower than they first anticipated to get a formal job offer. Life went on... still, i never could wrap my mind around Bond's straight flush of spades in Royale -- i at least had the satisfaction of witnessing four Aces delt in a single round, mine being uninsurable.

Break even or keep losing - for tokens. Now, that's suicidal.
