Go for Broke vs Saipan 1944

[Juiceman]

I purchased Elsenborn Ridge and Black Panthers recently and was thinking about Go for Broke as possibly my next purchase. But the Avalanche website says you must have Invasion 1944, Elsenborn Ridge and Liberation 1944 to play all of the Go for Broke scenarios. How many of the Go for Broke scenarios require maps from Liberation 1944 and Invasion 1944?

I'm also looking at Saipan 1944 as a possible next purchase. I would imagine that there is not a lot of maneuver in that game for the Japanese side, which should make it a good solitaire game. Does anyone out there play Saipan 1944 regularly? The maps are gorgeous.

19 of 29 need Liberation while 9 of 29 need Invasion, that could be a combination of maps or counters, if it is counters you can sometimes get away with using counters from other games as long as they are of the same country, maps are a different story. 
Give the Pacific a try, especially since you are interested in mostly infantry, I have Saipan but have not played it, it gets a good rating from other players, one of these days I will be back to the Pacific, started my PG fixation with the Kokoda Campaign but have been bogged down in Europe with a brief stop in China.
