Editing Tech Cost

[Eger]

I tried editing the Tech Cost of every tech to make progression much slower but everytime I load a map the game crashed? Any reason why? I tried editing both the Technologies.xml but to no avail. Any help would be appreciated!

You probably caused some kind of syntax or database error. Also there is a much easier way to change the cost of techs than to do it with every single one manually - and doing it dirty in the game files. Take Gedemon's example:

Using just one line of SQL you can change the cost of techs to your liking:

UPDATE Technologies SET Cost = Cost*3;

That would tripple the cost.
