1 - Xeno series (gears, saga and blade) -> Xenosaga episode 3 = best game ever (masterpiece stories beyond what a human could ever expect, Saga > Gears > Blade, but Blade has the best gameplay)
2 - Metal Gear series (mindblowing plot, great gameplay, absolutely brilliant series)
3 - Souls series (brilliant minimalistic story, perfect combat system)
4 - The Witcher series (3 > 2 > 1, fantastic plot, gameplay, characters and quests)
5 - The Elder Scrolls series (amazing world, the stories can look not amazing on their own but when linked to the lore they become great, gameplay is awesome but has some serious issues)
6 - Final Fantasy series (IX = Tactics > VII > XI > X > VII: Crisis Core > IV: After Years > IV > XII > VI > VIII > X-2 > V > III > I > II)
7 - Kingdom Hearts series (I admit I played this years ago and may change my opinion. Great plot, the gameplay of game 2 is fantastic)
8 - Chrono Cross (amazing OST, story would be a masterpiece if not for some plot holes. I like Trigger too, but not as much)
9 - Okami (amazing OST, creative story and gameplay)
10 - Shadow of the Colossus (amazing atmosphere, great minimalism, beating down colossi is very fun)
My visual novel list:
Fate/Stay Night ---- 10 ---- (Be warned that watching or reading Fate/Zero beforehand spoils a lot of things) An amazing story with the best magic worldbuilding (that is even more expanded with the other stories from Type-Moon), a very crazy storytelling broken in 3 routes, where each introduce plot points, characterization and foreshadowing for the twists that appear in the next ones, and each route is focused on different aspects. It's a story that exceeds in having tons of well-written twists (you MUST play the routes in order and also look at the Servants' stats to understand their abilities, otherwise you may be thinking there are asspulls), great themes of altruism, justice, giving a meaning to life, morality, what is evil (in a unique take, you'll know what I mean in Heaven's Feel), redemption, responsibility, etc., and all the important characters are excellent, although only some of them are fleshed out immediately in the first route, most take time. The fights are amazing and well detailed, and the art and soundtrack are impressive. And of course the fantastic gameplay, with many choices that lead to unexpected bad ends, I suggest you don't use a guide. Some pacing issues and a few flaws, but I'm rounding up the score.
- Fate -------------------------- Slow start due to mix of slice of life and plot, some good fights spread around but really not that much of an engrossing story, romance starts weak but really picks up steam into good drama, Saber's backdrop and development are fantastic, the last days have unexpected well-written twists and an intense climax. Shirou's epilogue was weak, but Saber's was great. Some points are unexplained or discarded, but they're left for the next routes.
- Unlimited Bladeworks -------------- Much more engrossing story than the first route, with lots of twists, fights, alliances and planning. The supporting cast is much more fleshed out and plays a much bigger role. Many questions from the previous story are answered, but still not all of them. The romance is inferior to the first route, but the story still gets very dramatic due to Shirou fighting for his ideal against Archer and Gilgamesh, Shirou also actually becomes stronger than in the previous route. There are 2 endings to this, I liked the true end better as the romance was focused only on Rin and gave perspective for the future, while the good end was kinda messy in the romance aspect and it's short-sighted. There is a fight with a weird outcome that fortunately gets better explained after the credits.
- Heaven's Feel ----------------------- New plotlines are introduced that answer all the questions that were left, characterizes the remaining characters and add even more layers to the ones that were already set, the Holy Grail War is stomped on and everyone die like dogs with twist after twist, it gets a bit slow in days 11-13 but it gives time to pay off. The drama is great, the revelations are mindblowing, where nothing was what seemed at first, and characters (that don't die early) develop fantastically. The last fights are absolutely epic, that apocalyptic feel. The true end is happy but well done and emotional, while the normal end is... sad as fuck. Really. I recommend you see both.
Fate/Hollow Ataraxia ------------ 8 ----------------- The story itself is pretty good, nice mystery and twists, and further develops interesting plot points of the series, as well as the characters. Those whose pasts weren't fully explored in Stay Night get focus here.
However, over half of the novel is slice of life. The good SoL scenes are much better than all of those in Stay Night, with good character exposition and interactions. But the bad scenes are... so bad you'll wanna skip them. Repeatedly small talking about food and clothing, seriously? I can't stand that.
Saya no Uta --------------------------- 10 ----------- This is extremelly SICK, but also incredible. Great introspection, character development, plot and horror. You've gotta see both endings 2 and 3 to fully understand the story. An excellent psychological with a very original plot and masterful writing, a masterpiece.
Sono Hanabira ni Kuchizuke wo ----- 7 -----------You've never seen real cuteness until reading this. Great sex and good romance.
Sono Hanabira ni Kuchizuke wo 2: Watashi no Ouji-sama ---------- 7 ----------- Better characterization than the first, but the sex scenes weren't as good, and they were also more poorly placed.
Sono Hanabira ni Kuchizuke wo 3: Anata to Koibtito Tsunagi ------------------ 7 ---------------- Easily the best couple, but... it seemed to me it was too short, but I didn't time how long it took. Maybe I just enjoyed it so much it went by quickly?
Danganronpa ------------------ 8 ------------------------ Very good mystery with an intriguing gameplay on the trials where you have to put the pieces together, last chapter was awesome, but it has some dumb points that could've been better. Some stuff is still ambiguous by the end, but there's a sequel, the story isn't finished yet. By the way, the anime is a bad adaptation.
Danganronpa 2 ------------------ 9 ------------------------ You get everything that made the first game good and make it EVEN BETTER! ...Except for the execution scenes, that is. Most of them in this game are lame.
But other than that, it's amazing. The cases and trials are better made, less predictable and more complex, while the main story turns out to be even more twisted than the first.
