I've never encountered a resign hack in RoR/AoE but in AoK it is quite common. People made 2.0b in AoK so that nobody could cheat, but it has now been hacked so is pretty useless. It has also caused some wierd separation, where inters + use 2.0b and Grooks and below play on 2.0a, it's quite bizarre. I have encountered very few cheaters, but people seem paranoid that everyone is a cheat.
The resign hack is so pathetic, it basically makes you resign as if you actually decided to, when it is the opponent that is making it happen. I guess it is useful in more than 1v1 games but it's very stupid in 1v1, I think the player it is used on will know they have not resigned. In say 2v2, you would probably know too, when your ally resigns for no reason.
Heres a couple of maps I played today: RM Hills - My opponent got an area that was easily walled and I was left out in the cold. They also got all the resources. I got a 13.5 min bronze (very good for me), raced in, but when I noticed the walls I was screwed. They had ranges outside and I was quick to be defeated.
Another was random footwar. Why do people play it? If you get a better civ you win, whoopdie doo. I know the random element is exciting, but in 1v1, which is what I played, I got greek, they got minoan. By the time I had a lot of cents the map was covered in ranges, and I couldn't do anything except lie around and die.
Well that's enough moaning, it wasn't cheats that caused those problems but the result was the same, the feeling you never had a chance. In AoK the maps are less random thankfully, and the civs more balanced. Also they don't play "Legion War" etc in AoK
