I imagine most of the game will be like ME 1 in the sense that whenever we go planet side somewhere we will be dropped off in the mako but I would still like for there to be a shuttle on the Tempest in order to reach those types of terrains or environments where the mako is just not going to work. I know it won't be controllable and just be used mostly for cutscenes but I still liked having them.
Edit: It should say the instead of then in the thread title but I guess it can't be edited once posted.
I'd love it for another reason, too (but my hope will probably be in vain, again!):
I'd want to be able to either leave the ship under the command on a companion (who will do his/her own mission - while I do mine, with a switch between two teams who are acting more or less simultaniously!) or send the shuttle (or shuttles, the SR2 had two shuttles (or at least room for two!) after all) out on missions (maybe back to get reinforcements etc. too!)
Also - but they aren't giving us that either (Mako only -.-): I'd want to use the shuttle to scout a planet (why drive if you can FLY?) and I want to fly the shuttle MYSELF! (use the guns, land whenever and wherever I want etc. etc.)
