I've got the HD mod from steam forum. But the graphics would feel too slim for now, I guess I've gotten too used to playing it on widescreen monitor without HD resolution. I have since reverted back to non-HD resolution.
You could say it's cheating, but these are ways to make the game even more fun for us. Cheating with the gold and goods will most probably remove the fun from the game, but removing the limit of city building number will undoubtedly add more fun for most players.
Though currently I'm still looking at how to modify the goods production of new towns.
I found that some Chinese softwares called P3 Insight is able to do it, however it only works in Windows XP. It is quite a bit of work for me to search for the correct memory address for city goods production in Cheat Engine.
I would like some insight here if anybody knows: the alt tab issue (the game keeps crashing when alt tabbing in win 10). I tried several things, like various compatibility modes, analyzing logs and whatnot but ultimately I didn't find much useful info (apphelp.dll will ultimately crash, but this is not the source of the problem; it is just where the game dies).
Not sure about you, I'm able to alt-tab in Windows 10 to use Cheat Engine without issue. All I had to do is just ticking the box that says "Override high DPI scaling behaviour", which is just below the compatibility modes. Did you try this?
