I'm torn here. I really want to like Platinum's 'character action' games, but I just don't. At all. And this is as an action fan, who replays all of the Devil May Cry games regularly.
Raiden in MGR just wasn't fun to control. He was too heavy, and ninja run is awful. It's really clumsy, and I don't like tying one specific type of blocking (bullets) to it. In the middle of a fight, if you wanted to block bullets, you have to do the sluggish sword-sheathing animation and start running. But you end up having to use ninja run for dodging and basic traversal as well, because Raiden has those Jensen Jumps that can't even handle most of the game's terrain.
I also felt his moves weren't...'distinct' enough? In Devil May Cry, Dante has a very short basic combo, and every hit is immediately recognizable. This really helps with combos, and getting the right attack out. If I have tap-delay, a tap-tap-delay, and a tap-tap-tap-delay strings, it's good to be able to recognize what the first second and third hits look like. Raiden's basic X button attacks felt too much like arkham where it's just an endless string of the same attack. I don't know what Raiden's second X looks like as opposed to his third or fourth. So instead of being able to see it and recognize all my strings, I just have to count out my button presses.
Plus, I thought the parry mechanic was really awful. It's fine during normal gameplay, but it makes the boss fights a joke. I've beaten it on normal and hard (side note: I've heard it's better on revengeance, but a good game feels good on any difficulty, and I doubt adding more enemy damage would fix my issues with the game's design. And if it really does fix every issue the game has, it should be unlocked by default.) and I've never died to any of the humanoid Winds of Destruction bosses, including Sam. The big red flash is fine when there's a group of normal enemies, but when it's a 1v1, you just need to press the stick towards the enemy you were already attacking.
I'm pretty sure I make one of these posts whenever there's a Platinum thread, but fuck. The game has such a great soundtrack, and I love all the dumb storyline stuff. It's purely an issue of gameplay. And also the platinum self-fellating, but I'll save that for a Wonderful 101 thread.
