It's a broken jank fest of a game, but it's also fun and endearing. Very glad I grabbed a copy last time I was in Japan.
You weren't lying, haha. Finally played City Shrouded in Shadows over the weekend and you summed it up well.
It felt like a more ambitious Simple 2000 game with better graphics and much bigger IP attached. Like one of those budget titles, the idea of the game is better than actually playing the game but you can still have a ton of fun with it. I think you'll get the most out of CSiS if you're a big Kaiju, Ultraman and Anime fan (particularly Evangelion and Pat Labor).
CSiS It's buggier and the gameplay is more trial-and-error than DR4 since it relies heavily on QTEs and the action takes place in the middle of monster attacks instead of their aftermath. Load times are short enough that it's not a big issue but there are sections that can test your patience. The camera can be hectic at times and it often jumps between 1st and 3rd person in cramped spaces.
The game is broken up into 17 very short chapters that focus on one monster scene and location. You mostly run away and dodge out of the way with timing-based button presses. There are also slower sections that break up the action where you have to figure out the combination to a keypad or play cupid for a lovestruck vice-captain. And then there's a generous amount of short vehicle sections that constantly switch things up.
I was surprised how much of a DR game CSiS actually is. It opens the same way as DR4 where you pick your gender and are asked a couple of questions that determine your character's backstory and their relationship with Yuki, the main companion character.
I loved CSiS's sense of humor. The game is intentionally funny. It knows you're here for the B-movie flair and plays it up. The story doesn't make a lick of sense for most of the game but a reveal during the end credits kinda explains all your lingering questions.
Like in the DR games, there's always one funny/ goofy/ stupid/ aggressive dialogue option that will lead to confused or angry responses. 8/10 times, I went with the goofiest outfit and the dumbest dialogue choice available and I have no regrets. There are silly sound effects like cheering when you level up your stats, shameless Go Go Curry product placement or in-game advertising for Granzella, their own game studio that they also make fun of. It's hilarious how some people are maybe slightly flustered by the giant Eva Unit fighting a huge Angel a couple of meters away from them but still continue to go on with their business as usual.
The 17 chapters are very short, I think I would have preferred fewer but more fleshed-out episodes. The game is pretty linear but exploring during quieter scenes will often be rewarded with coins (used to level up stats, buy outfits & haircuts during chapters), items or even small cameos with characters from previous DR games. Talk to everyone with a green speech bubble, those conversations lead to sidequests or collectibles. I think it took me 8-10h to finish the game and I did a good amount of exploring.
Overall, I preferred DR4 but still had a good time with CSiS. I think it's worth playing for DR fans, especially if you're also into the other guest IP.
