Making three extra characters from the ground up is VERY hard work along with 4 extra cutscene, (though I don't think 2 of them will make any significance to the story). I really was surprised when they announced that Lady and Trish were playable, including the trailer. So I really appreciate what Capcom has done.
But I'm afraid that, even after seeing live-streams, gameplay footage, and seeing updates, I'm still deeply disappointed so far. I hate to make a comparison to a game that not everyone has played, and most of the fans hate. But DmC: DE (despite it's glitches) has right now the type of content IMO that would make the game last for a long time, it fixed most of it's gameplay mechanics, and at the same time add modes, tweeks, plus having free DLC from the vanilla that would change the game's feel of the combat and difficulty through-out. You have Hardcore that's making rank in combat and missions much harder now (make it even harder with no upgrades on all your moves), add Must Style and it even makes Heaven&Hell fun to play (again, no upgrades), and add God Must Die (and again, no upgrades). You can experiment with the game in ways that you want. Including the fact that you can take the timer in BP off or on to challenge youself. This may not be as hard to work with compared to DMC4:SE's 3 extra characters, and 4 new cut-scenes. But it's still huge significant change from the original that would make the game last til the cows come home.
Despite all the characters they added, and more cut scenes. What else did they add in DMC4:SE so far?
-LDK
-5 Costumes (only one for each character from what I've heard so far. 2 that are pre-order bonuses (if you don't, you have to pay for them), 2 that are IMO...meh, and just one that is pretty awesome)
-Turbo
-few gameplay tweeks (that seems to make the style meter easier to get an SSS, speed activities faster, and bigger hit boxes for crowd combat)
However, the problems in DMC4 are bigger than the glitches I might encounter in DmC
E: Repetition, and limitation. You can have a very well polish, functional game, but it can still be a turd (not talking to you DMC4, I'm looking at you DMC2)
Now, DMC4 has the biggest and the best character gameplay in the series IMO. But the problem will remain. They didn't fix the backtracking or make any significant changes to the repeated level design. Now with three extra characters, you'll be going through the game 4+ more times with the same songs from Nero and Dante's campaign. I don't know if PS4 and Xbox One can still allow custom music in game just like the PS3 did (don't know about Xbox 360), but I think DMC4: SE will need that feature. Otherwise, the gameplay will get repetitive and stale in about a year or less. Plus unless modes like Hardcore (which after looking at DMC4:SE's style meter and mission rank, the game NEEDS it), Must-Style, or when they make all the enemies in DMD devil trigger very quickly, there isn't much to experiment nor challenge yourself.
They didn't atleast get rid of the timer which was something I didn't like in the original, nor did they say anything about a training mode.
Now don't get me wrong, I'm not against DMC4, I still love DMC4, and when I get a PS4, this and DmC
E will be the first games I'll get right away, But I hoped for a bit more than just adding new characters (you do have LDK mode, but it doesn't look very hard when playing as Vergil, Lady, and Trish. I've yet to see Dante and Nero though). I do hope more modes will come as DLC awhile after the game's release atleast (and we don't have to pay for it).
