Could you please give us handicap option in scenario editor as it is in the 1.6 game data to the 1.5 game data, so that we can use it in the <=1.4RC patches which allows AI to build TC in any maps!

UP 1.5 as well as UP 1.4 is a project of the AIScripter Team -- we only provide support for our own projects. Sorry.

Can we implement it in the in game option along with team together, Full Tech tree and others?

No, you need to use community patch 1.6 to access these features.

And this patch is not built for AI gaming.

I don’t know a lot about but I think the patch uses a modified version of promi ai.
Apparently Juggernaught ai is a lot better.

Of course it is not, all those User Patch / Community Patch projects had their focus on multi player.
