That wasn't only Ren's comp freezing - so did mine, after I had built a radar or blab - I had run over the Prerequisite= changing everything into generic RADAR,TECH, blah... and the radar or blab would unlock enough units to actually overflow the 74 limit.
The AI built their buildings just fine, as I remember.
"But i was just wondering whether there is a way to change the game in RA2 so that you can ally with the computer in co-operative cause otherwise it is just like another Battle setting and rather boring."
On another note, after i unlocked all of the game modes, i created a map in fa2 and checked all of the availability box things (you know what i mean the "meat rinder" etc.) but the game would not let me play i in a megawealth game. does anyone know why?
