Shin Megami Tensei IV
It's a rollercoaster of reactions, my first impression was weak, repeating the same area for fetch quests, the difficulty spikes and kind of lost with what to do or where to go... The story and characters also doesn't impress (the voice dub doesn't help) but 16~20h in and it's getting more interesting (to those who played it, i'm in the new zone).
But then starts the fusion system with the "pokemon" must capture all mentality and this game is pure crack, you can argue that you don't feel attached to your demons (unlike pokemon where you had at least 6 favourites) but since you can pass along the skills to the new demons (fused) it doesn't matter, you want to capture more demons so that you can fuse and get new ones.
My grip with the game is the difficulty, it's all over the place, the regular combats are ok but when you get to a boss then the game goes all bananas and you die in one round. Hell, even in some combats you're at risk of being killed by some "enemies" that use barrage and take half of my team health, if there's two of them using barrage then it's game over (yes, game over, i'm not going to pay to come back to the game).
I'm not gonna lie, when i have that alert that a boss fight is coming i switch to the easier mode, i don't mind fight's that take a while to beat because the boss has lots of health or transformations but screw that shit of them being able to kill your party with few hits, i'm not going to grind because of bosses.
Having said that, i'm happy with the game, slow start and crappy difficulty spikes but addictive gameplay (and a somewhat interesting story) makes up for that.
