No Reserach
 

Is there any easy way to mod the game so all research up to level 7 is available at the start of the game and you cannot research levels 8 and above?

I´m using the lates CBM + single age mod, with the latest patch.

thanks.

Edit:

Also, is there any way to restrict the building of castles? I want that myself and the AI can only use the starting castle and castles found in sites....

Spell modding so that you set all the spells you want to research level 0 and all you don't want to -1 (unresearchable) should do the trick for spells.

The castles, no. For that, you would need Dominions 2, where the AI did not know how to build castles and was therefore always easy to beat. Had nothing but hordes of indies too. That was the #1 complaint about Dom2 for SP players.
