So here's the thing about this question. I played it once (albeit not very far) when i was younger and i was really terrible and not patient. but i played new Vegas and loved it. I'm really undecided about this and was wondering if anyone else had had this same issue?
Fallout 3 has great exploration but lacks in the side-quest department. It doesn't have Ironsights but that's a minor issue. If you would get it on PC and its able to handle it, then you can expand gameplay with mods.
