I'm not sure why people think that the return of the Mako and planet exploration means it's going to be the same exact thing as it was in ME1.
If they can improve the control of the Mako and make the planets more unique than a different skybox and ground textures (because that was the only differences between barren planets in ME1) and make them fun to explore with different kind of buildings, caves, enemies, etc. who wouldn't want that?
I realize that all three past ME games are different from each other and because of that the fanbase is divide, but surely planet exploration done "right" can be interesting to everyone.
