FC + kts can work well.. but imo its better in 1v2 format.. Vs 3 or more, you need more powerful units. Its not like trade is a main concern when gold is still left to be mined.
Indeed, in a 1v2 I already sucessfully used the knight rush. Against 3 I would have to set priorities i guess and go for the strongest first. Something like first 3-4 knights go to the strongest, next 3-4 to the second, next 3-4 to the last and then add one at a time or whereever i face more resitance. That way it might work.
When I play(ed) with my friends I used to go for late imp with mongols massing mangudais but they are so expensive and slow to mass that by then even my noob friends would have a decent eco and decent army and I couldn't afford to lose many mangudais otherwise the gold would indeed run out, then I started going kts/ca (if you can micro 2 small groups of CA, I recommend those coz kts always get hit fighting pikes but you can easily keep CA's untouched vs noobs) and harrassing the one I knew that was the best player and the weakest one (the game would turn into a 2v1 for a long time). More recently I tried to do the conqs + fwd castles but it didn't work because one of them can already reach castle under 20min ( :lol: ) but I think it could have worked if managed to stall him longer before he clicked to castle.
PS: Maybe you could try mongols in Double or Triple Arabia :D :D
PS2: Make sure you let us know how the games went
