Devilmaycry 1 was definitely the hardest game and the best (story wise) took me about six months to complete Dante Must Die mode, none of my mates beat that mode they copied my memory card (the bast***s),
Devilmaycry 2 I beat with a mate it was his game, we beat it the second day he had it, he beat Dante Must Die mode in a week or less.
Devilmaycry 3 a strong rival for best game it was tough enough but not as hard as the first game, it took two or three weeks to beat Dante Must Die mode.Toughest fight with Vergil at the end, even tough on normal.
Finally Devilmaycry 4 on Dante Must Die mode I tell yiou in my opinion, is nearly as tough as the first game at certain sections, that electrical demon Blitz is harder to kill than most of the bosses, Dante's one tough motherf**k to beat, I had to keep jumping and striking down and using the horizontal attack with Nero, it is a cheap tactic and it just barely works .( stuck on level 19 on Dante Must Die )
