My two favorite games for some time were Lego Island and Lego Loco.

Lego Loco is a city builder and railroad builder game. Something like a more basic SimCity and Railroad Tycoon crossover maybe. I really liked Lego Loco because you can build a whole city out of Lego to your own liking.

So I had Lego building in Lego Loco and I had Lego Island with all the fun stories and things you could do there, like chasing Pepper the criminal with a helicopter and using donuts and pizzas to help the police on ground and the skateboarder.
