In order to use World at war you will need the original or Pacific. I think the best game is a combination of Europe and Pacific on the World at War Map. Although I think Europe and Pacific did the oceans much better. Maybe I need to make my own map!
I saw that Tiger before when I was looking for R/C tanks for my boys. They ended up with a set of 1/16 Airsoft Panthers. Very cool. My favorite toys we have right now would have to be our 1/32 slot car track. When we set the whole thing up it’s over 100 feet long. It takes up a lot of floor space to say the least.
