I got the second golden sun in a stocking for christmas and my parents bought it at a pawnshop for like 5 dollars had to wait forver to find the first one and to do a djinn completionist run.
ME1 is actually my favorite in the trilogy haha, I've got a few tips that might make getting through it easier. #1 you can do the main missions after the Citadel in whatever order you want so if for example the ice planet is holding you back do one of the other ones instead, Liara's world is pretty straightforward and usually the one I would start on. #2 pick a class with biotics, the actual gameplay is so much funner when you can ragdoll the enemies around with the different powers. #3 when you're in the Mako you get less experience for kills so you can get a nice xp boost by hopping out right before killing bigger enemies and finishing them on foot. #4 having played through the game on the harder difficulties there's no shame in playing on easy or something to make it easier to get through, the only difference between the difficulties is damage levels as the AI definitely doesn't any smarter
