Lego games have always sold well across multiple platforms. At certain times, they sell better on one platform than another.

The latest next-gen comparison would be Lego Marvel -- which sold best on PS4 compared to WiiU and Xbox One. But historically in the last gen, Lego games typically sold better on Wii and 360.

My vote is for Wii U -- as that platform caters to the Lego gaming demographic best and for the fact that this only one of two retail games available for WiiU coming out this month.

Last gen Lego console games sold better on 360 and now a lot of those 360 owners migrated to PS4, so the PS4 version will sell better. Lego Marvel for example.

will they cap the PS4 version to 30fps again?

I think the PS4 version will sell better. The WiiU and XboxOne version will be closer to each other.

Anyone tried a co-op Lego game with the Wii U gamepad? To me, that'd solve the never-ending problem of split screen in Lego games.
