What exactly makes a video game difficult or not? A lot of it comes down to personal experience and opinion. What I think is easy or hard, someone else might struggle or breeze through. There does seems to be a general agreement on hard video games. Battletoads is often noted as being nearly impossible. The entire Ninja Gaiden series from its beginnings on the NES to recent games on the PS3 and 360 are always a challenging experience for even seasoned gamers.
Easy games are more difficult to pin point, I think. There seems to be some games mentioned a few times like Yoshi's Story. But when trying to come up with an "easiest games" list. I had to ponder the topic a lot longer then the "hardest games" list. I included games like GunGrave and Lord of the Rings Conquest. I wonder if these games were as easy for other gamers as they were for me.
Take a look at both of my Hardest and Easiest video games list here and see what you think:
