No it is the only sequel... anything released in-between the timeline of DMC1 and DMC2 is mere filler like Resident evil:lost in nightmares&revelations..
Lost in Nightmares was an hour long DLC, hardly a sequel. And Revelations isn't necessarily a filler because it takes place between RE4 and RE5. It still is a full length game and continues to push the story forward. Plus RE always or most of the time has a different protagonist is each game. So comparing that to DMC, which basically has Dante as their main guy is hardly a comparison.
As for DMC4 being a filler, yet having (4) at the end of DMC basically makes the game part of the universe and it does take place in its respected time, which is after DMC1, not a sequel like what you said, but not by the definition of what you said. And DMC2 is a sequel to DMC1 because of the simple fact of it having a (2) after DMC. DMC2, from my eyes, is basically the
last game in the series, and the only reason why is because Dante is at his oldest. There is nothing DMC2 does to continue anything from DMC1, besides having Dante in it. The introduction of cool gunplay and another playable character, which DMC3 and DMC4 had, completely throws DMC1 under the bus, because it seems Dante is a lot stronger when he was a kid. And then he forgot everything in DMC1 and then remembered everything again in DMC4. (such a mess)
What i really know is the continuity of the original games take way to much effort to understand. And when you play them chronologically in order, you better be ready for the onslaught of face palms. Which is why i wouldn't want Capcom to have anything to do with a Sparda game, besides funding a better company that know what their doing.
That's one theory; that Dante received energy that he could form into the weapons, since Sparda isn't necessarily depicted with using the Arbiter - although he would certainly have the potential to have, considering he was using the Rebellion before he gave it to Dante.
check out that sword. Is that supposed to be rebellion, or is the shield supposed to be rebellion? or are they both rebellion? I'm sure Sparda could have the potential to make an axe, but this picture kinda shows you the type of fighter he was and the types of weapons he would use.
I think its awesome that he uses a sword and shield. But like you said, since he used them before Dante, there is a possibility that Sparda could wield an axe. And that shield could be used a Sparda game as the Royal Guard, plus he could have Yamato and Rebellion, that's 3 stances, that's a new game folks!!
I just like the idea of Rebellion taking the form of whatever the user feels comfortable with and is best at.
