If you play these 3 games, start with the first one and then move to the 3rd one which is the prequel to the 1st game. The 2nd game is a separate story made by a different company and it has nothing to do with the 1st and third so just skip it, TRUST ME, it's horrible!
eh honestly 2 wasnt the worst game i ever played it was stupid easy and incredible forgettable but in its own way 4 pissed me off alot more nero needs to die i play dmc to see dante kill demons not some whiny wimp thats scared of his own arm if they have to have two characters it should be like it was in 2 and 3 each playing the whole game with changes not dante getting less then half the levels so ya lucia > nero virgil > nero to be far i do like 4 i just hate how dante is on the sidelines it would be like if they made megaman 11 and u played the whole game as roll or something it would be different and maybe fun but u would miss the character you were more familiar with and they may even make u pay extra to just be able to play as megaman like bass in 10
even if i never played this series or even the MGS series (which has the same chronological stupidity), i would never do them in chronological order. i like to experience them in the actual order of release.
DMC2 was OK, I just hate the idea of constantly disc-swapping every few levels. I remembered back in the day, when I tried to unlock the Diesel costumes (pic here: http://tinyurl.com/6usa5m7), the only way to unlock it is disc swap every freaking minute. It was a huge pain in the ass. Other than that, the game wasn't that bad. Lucia was annoying as hell, though.
I kind of wish the DMC Collection for PS3 would use the original difficulty levels of DMC 3 as opposed to the special edition version. The original DMC 3 was far more intense, and I think it was just more fun that way. Either way, this will be a good release.
Also, DMC 2 wasn't really a bad game, just extremely easy to beat. Just shoot everything and you win!
