Snow Girl, I don’t know how you actually feel about RPGs, but I’ve noticed a few classic omissions from your lineup. First off, I need to echo the sentiment of the original Grandia, for either your Saturn (if you don’t mind importing) or your PS. It’s a lovely game, perfect for people that usually shy away from the genre. It is devoid of things like illogical/overly-complex development systems, angst, thousands of random battles/endless grinding, and myriad other faults the more typical examples of the genre possess. It’s an exceptionally warming, fun experience and feels like the game Miyazaki would make. I’m not actually partial towards anything else in the series, nor anything else GameArts did after Grandia. I feel it stands as the pinnacle of classic GameArts.
Chrono Trigger and Secret of Mana are pretty essential if you have an SNES. For many of the same reasons as Grandia, actually. They’re fun, unpretentious, inventive, and they side-step many of the pitfalls that other genre examples so often don’t.
I could reccomend more (such as my all-time favourite game, Vagrant Story, and the Shin Megami Tensei games on PS2 are highly creative if one can stomach a grind), but I want to get a better feel for your tastes in regards to the RPG genre.
I’m going to echo Castlevania: Symphony of the Night. I respect a lot of Nintendo franchises for establishing certain ideas, but there really aren’t any first-party games from them in my lists because I feel they constantly get one-upped. For my money, anything 2D Metroid ever did, Symphony of the Night does better. Zelda is an ace foundation, that games like Skies of Arcadia (Dreamcast), Beyond Good & Evil (PS2, Xbox), and Okami (PS2) build upon to a much greater effect. And although Mario can be decent fun, it is merely the rough draft to Rayman 2: The Great Escape’s (Dreamcast version=the definitive) final copy. As a result of this, the only Nintendo console I care about owning is an SNES, for its wonderful third-party support: the 'cube is expenable, and I’m not yet sold on the Wii.
I can’t recall if it has been mentioned, but I feel that anyone who owns a PS2 owes it to themselves to play Ico and Shadow of the Colossus.
Also, I’m going through Metal Gear Solid 3 at the moment and it’s unrelentingly brilliant. It’s a gloriously-paced origin story, so if you have no previous experience with the series it is a PERFECT place to start. Its mechanics are wonderful, for the first time in the series the environments are organic and completely absorbing, and the plot finds a perfect balance between realism and fantasy and doesn’t get bogged down in its own cleverness like the almost aggrivatingly “post-modern” MGS2. In other words, to anyone turned off by the second game: MGS3’s writing is pretty damn good. I personally really enjoyed MGS2, but 3 is definitely shaping up to be its superior in the end. It took me this long to get around to it only because my previous copy would always freeze after a certain boss fight early on, so I’ve fiiiinally been making real progress since picking up the Essential Collection. That actually brings up another point: the Essential collection has recently released, which contains MGS1 for the PS1, and the director’s cut versions of MGS2 and 3 for the PS2, all in one collector’s box for $30. If you haven’t played them, now’s as good a time as any.
For the record, I don’t yet own a PS3, but a friend is perfectly willing to rent me his for as long as it takes me to finish MGS4.
EDIT: Just wanted to mention an all-out action title, since Ninja Gaiden was brought up. My favourite action game of all time is Kojima Productions’ Zone of the Enders: The 2nd Runner, for the PS2. I don’t care much for the first ZOE (it was a tech demo for the team to figure out how to run MGS2), but ZOE2 is an ultimate sequel and it requires no real knowledge of the first title. You can jump right in. I’ve never had a more exhilerating experience with a game in my life.
