My guess is Dark Chronicle/Dark Cloud 2:DamianWinters said:Ive been trying to remember what this game was forever, I don't even know if it's real might just be a dream I had. But anyway it would be a Ps2 game out in the early 2000s where you are a young boy, you live in an old fashion town like steampunk era with a scientist (might just be your dad) that you get a robot from or you make it yourself (the robot only covers the bottom of you so your upper body sits on it, it was rust coloured and quite large, like this http://smg.photobucket.com/user/tamanade/media/Iron%20Warriors/Steampunkwalkingtank.jpg.html but with arms on the side and no cannon top bit instead a circle with a seat and levers for the boy to control) the robot is upgradable with different weapons one a few I can remember being boxing arms and another a railgun I believe. You can take it out in a jungle area. I remember one part were you have to either collect or take a picture of two large milk bottle containers next to some steps outside a house.
Hopefully that jogs someone elses memory aswell.
