Is it really that complicated from a legal and support perspective? For legal/platform compliance I feel that it shouldn't be that different between platform, most of the work should be the initial familiarization with the requirements or are they changing all the time like crazy?
Support should be proportional to the number of users.
If the game is multiplayer/ live service I see that things might get seriously daunting if you don't have either a good number of sales or the capacity to coordinate the whole team.
