Hmmm...How's about something like :''Tales of Sparda'' or ''The Legendary Dark Knight''...however they should keep the ''Devil May Cry'' title cuz it still belongs to franchise
Anything would do fine other then '5' in fact i also think that DMC4 should've been called as
DMC: Fallen angel returns (nodding towards Nero returning as Nelo-Angelo possessed by Vergil)
and i would so so love to see demons as strong as Sparda because i'm sick of capcom making him look like he's the only Demon who's got some balls its would be neat if they just relate nero to sparda's brother or someone else
