Does anyone know if there's a "sweet spot" in the game settings that gives the AI its best performance? I play DL 1.5 at Tough difficulty, usually in a Medium sized galaxy. I've been playing with all random settings in my last few games. Every one of them has been "over" long before victory is achieved. The AIs simply cannot match the strength of my economy. I start every game by deficit spending to stay at 100% morale until the cash runs out. Once I reach the "turnover" point I'll be middle of the pack in every category except population - I'm way ahead there. Having a much larger tax base allows me to win however I choose.
I really like the fact that the AI kept up with me at first without cheating. That's why I haven't bumped the difficulty level any higher than Tough. Should I invest in DA to get improved AI? Would having more/fewer planets help the AI along? For that matter, does number of opponents affect anything? Now, I'm not looking for the AI to actually beat me, but I would like it to keep pace a little longer. If I've conquered half the galaxy I'd like one of the players to have at least conquered somebody.
