L29Ah is lucky in most games to degree of guaranteed victory. It's an objective fact. Even in last game where I got overpowered Huns - random placed him on separate continent to save him from harm, while everybody else except for maybe one AI was placed on our continent to prevent me from rising to real power. Coinscidence? Could be. Coinscidence 4 out of 5 games? I DON'T THINK SO.
Isn't he on a different continent than you in that screen shot?
Isn't your start is really good in that screen shot? .(pearls are amazing in this mod)
Are you settling your capital well?
You had a lowish hammer start, how did you address that? Early fishing boats, animal husbandry and mining? If you took progress, an early construction tech, stoneworks and quarries will bring those stone up to 5 hammers each.
Are you playing into your civs
What is your pantheon? Were their better choices available?
It looks like you spent a lot of time having your workers make farms on those grassland tiles, that is a really bad move on this start. You just aren't making sense, if the start is so bad because low hammers you don't build farms. You need to discover and improve those pastures ASAP, even putting a mine on the hill is a much better idea than a farm is (3 food is a bad tile, even the unimproved stone is probably better for this situation)
The overwhelming evidence is confirmation bias (a lot of player would prefer to be put on a continent with an AI, eat him and take all his land)
The other thing to do that addresses all this random thing, that has been suggested numerous times but seems to be the only thing you don't quote and reply to, CHANGE YOUR SETTINGS. Very few players will play continents type maps competitively. Epic speed isn't well balanced, civs like Germany or Arabia get no chance to do anything before early UUs win the game. Use a draft system (

Please, take the suggestions or stop trolling these forums. "You're wrong, I have just have bad luck, nerf this now" isn't swaying anyones mind (this is a clear fact, no matter how bad you believe your luck to be, you should be able to realize you aren't even close to convincing anyone else)
