I'll ask myself:
a DMC game that has the same exact gameplay of the previous game except new weapons or no DMC at all?
I have to choose the first option, the original DMC game was the first game I ever got for PS2, i probably spent hundreds of hours playing it. I kept playing it for one whole year before thinking of even looking at another PS2 game, maybe I spent a few months playing RECVX, that's when I started floating around the internet & massage boards, & a few months later I found out about DMC2.
the time I spent playing PS2, it was probably 60% DMC & RE, the other 40% was God of War, Silent Hill, need for speed, Gran Turismo, Final Fantasy, & Metal Gear. I never started varying until I got a PS3 & a gaming PC, since development takes longer this generation, I started buying games like crazy, Steam gives a lot of offers, & I never got stuck with a game I picked up by accident.
I think I kinda lost my point, what I'm trying to say is, I'd rather have capcom change the combat system every 3 games rather than not being able to play another DMC game. & I'm not looking forward to that point in time, I just choose to play a DMC game over not playing another DMC game again. so unless they change the main character permanently, I'd keep looking forward to the next game in the franchise.
I was never a million franchise follower, in the original PS days, I was a kid, everyone kept giving me games as presents, but I mostly played RE, MGS, & Dino Crisis. & I rarely spend 10 hours continuously playing video games, I usually go out most of the day, as soon as I get home, I start missing the last game I played, that's how my favorite games have such a high replay value to me, I still play the old RE, DMC, & MGS games. I bought NGC just for REmake & MGS, & I bought PS3 during the first week for around 1,000$ from ebay, I was looking forward to DMC4, RE5, & MGS4, since they were originally exclusives, & I never thought of any other game, they took years, so I started playing other games.
I never saw myself playing other games for more than a week back in the PS2 days, but I still want the franchise to drag on forever, assuming we still have Dante & the same genre, I don't want it to switch genre like RE did.
