Agreed. Every Lego game I've played is great, but Star Wars I - II are the best.
Also agree, the Lego games are fun, I play them on the Wii with my little brother when I'm at home. I loved the Batman one most and the Pirates of the Caribbean. Some levels can take forever, so they aren't short games at all.
Portal 2 was also great, but length depends on how quickly you solve the puzzles

might be too short for what you are looking for.
