Halo 2+3 on legendary, One specific nightfall gave me a lot of trouble once when I was trying to solo it. Battletoads.. never beat it but I played it a lot xD Ninja gaiden, don't remember which but it was hard af lol. Nfs shift 2 was hard for me. Last of us on grounded.. super hard xD Dark souls 1+2 were really hard until you get the bosses down and make a good build. I actually broke a controller one time lol. DoA 4
