Well, I didn't see this one coming. I have spent three days playing OpenTTD and forgotten about the world outside!
I started with OpenTTD because it reminded me of younger years with one of my favorites, Transport Tycoon Deluxe. And I just couldn't let it go. The images got burnt in my minds. The brain kept thinking about best strategies to build roads, run trains, earn money, even in short late night dreams.
Yet, I have so far not able to beat the Return on Investment ratios of AI players. Damn. My bus earns about 10 grants each year while AI bus earns about 30Ks. Why?
