Just as the topic states, I would like to develop a top-down 8-bit style game, but I have no idea where to start.

to be specific, i was wondering what type of engine i should use to develop this game with? And which engine or SDK would be perfect for developing this game for mobile. Any advice would help. Thank you! ^_^
