Surely just turn the difficulty up? If it's still easy on the top setting, then you've got something to shout about.
Its a Civ game, difficulty works rather differently here.
The middle setting, Prince in Civ V, Noble in Civ IV, is the setting that most people like to play at as at this level, neither the AI or the Human player have any advantages. Below the middle difficulty the human player gets advantages, and the AI gets disadvantaged, and at higher difficulty levels the player gets penalised and the AI gets significantly buffed.
However, in Civ IV, the AI was far from an easy pushover on the middle difficulty, and definitely very challenging at any setting abouve normal (thats how it should be right? Capable at noral, and harder higher up?).
In Civ V, on the normal setting (prince), the AI is as lame and dumb as playing on Chieftain in Civ IV.
However, one thing that I find that has really crippled the AI in Civ V isnt the 1UPT system, but rather no tech trading. In Civ IV, the AI was very competitive and powerful even on Noble difficulty because they tech traded with each other, kept up with the player, and provided a significant challenge on normal difficulty. In Civ V, they just get far far behind unless you crank up the difficulty to the point where they get 20 free units with no maintenance costs, and 50% cheaper buildings.
A strategy game like civ should be challenging and fun to play without having to five the AI a ridiculous amount of bonuses over the Human player, as it was in earlier Civ games. In Civ V, the AI is currently very weak and feeble. Its a joke when they cant even properly defend themselves against 3-5 units, and fall o far behind on the tech tree.
The other ridiculous thing is that the AI is so poor, that even if you dont conquer them, one of the other AI teams will. I ALWAYS see one single AI easily conquer all the others in every game I play, which is insanely broken, even more so now that I've learnt how to defend myself against the single super AI civ by using just a few ranged or siege weapons. They can have 10-20 cities, I can have 1, and I can still easily prevent them from conquering me. They hardly put up a fight at all, and then surrender a few turns later and give you all their gold.
Maybe I should reinstall Galciv as suggested.
