; use your new customized file.

; Note that the freeciv AI may not cope well with anything more

; Description of the ruleset
description = _("\
You are playing Freeciv with civ2civ3 rules:\
\n\n\
Gameplay more similar to civ3, keeping the combat system from civ2.\
\n\n\
Adapted for single player, with AI less aggressive at start,\
 but more challenging at the end.\
\n\n\
Detailed description of the differences from the classic ruleset can be\
 found in ReadMe_Civ2Civ3.txt.\
