Hi there guys! I wonder why the evil races don't colonize planets while playing Tough? The only thing they do is do build a fast military and then demand the weaker races to give them planets. It's sooooo easy to say no, and if u play with a lot of habitable planets, you will soon have a much bigger economy, technology and a good condition to build a HUGE army. Because of their bad research they will just have weapons like harpoons on their ships(lots ships though). Its easy to research defences like 10 weeks and then they can't kill your ships or even hurt them.
If you play Challengeing ALL races will colonize planets and ALL races will give some resistance, but on the other hand races will easily become your friends, making a diplomatic victory very common.
The games says that Tough is harder, but what's your toughts? Please wright and give som exemples if I missed them.
