I'd really love to vote for either Burning Rangers or Nights, but out of my very short collection I think I'd have to vote for Sega Rally, because..
1: Good old Arcade fun. 2: Quite alot of people have voted for it. 3: The cheesy music, catchphrases, etc ("Fiiiiiiiiiiiiiiiiiiiinish!!" "Game Over Yeeeeeeeeeaaaaaaaaahhhhhhh!!!!", etc..). 4: Great with the steering wheel. 5: Can't think fo any other reasons.
I nominate NiGHTS. Just what the hell is it with this game? It's certainly not a platformer, or a flight simulator... You can't really compare it to any other game. It's completely unique and original - in other words, sums up completely what Sega are about.
I remember the first time I played it, I was in a no fooling trance-like state! Zooming around at high speed (Sonic speed at times) colours everywhere, looping and weaving through the air... excellent game. And a sweet little moral behind it as well.
Currently playing: Virtua Fighter (Saturn), Sonic 2 (Saturn), Panzer Dragoon (Saturn), Resident Evil 3 (PS1).
One game! It's very challenging to select just ONE Saturn game to represent the Saturn. Here's a few I'm thinking of selecting from:
Sega Rally Championship No other racer is as playable. The courses, the car handling, the soundtrack, the graphics - all these superb elements meld together in a spectacularly cohesive form that is hard to put down. You can't have just one go of Sega Rally - you keep playing until you can't beat your times anymore. Even then you know you'll be back eventually to try again. The lastability of this title is extremely high, which is extremely rare for a racing game. Sega Rally is an essential title that belongs in every Saturn owners collection, whether you like racing games or not! It's both extremely cheap and common, so there's no reason why you shouldn't own this title.
Panzer Dragoon Zwei Extremely playable, and easy to get into. The world the game is set in is awe-inspiring, and the soundtrack, especially the way it fits every moment of action, only enhances the other-worldly feel of the game. Witness the quiet moments before the boss of Episode 3, before the music ramps up as the boss appears and begins it's assault on you and your dragon. It's graphically superior to both the original game, and Saga. The only complaint I have with the game is that it could use more stages, but there's enough of a challenge in achieving a 100% shot-down ratio on every stage, uncovering the various routes and dragon forms, and defeating the bosses as quick as possible to make up for this.
NiGHTS Into Dreams A very unique game, which oozes style. The graphics are still amazing to this day, and the soundtrack creates a fantastic dream-like quality to the games seven worlds. Gameplay is hard to pigeon-hole into any particular genre, but it is fast and fluid, and extremely addictive. Replayability is high thanks to the scoring based antics after you've destroyed the Idealya. A fantastic, original game that just has to be played to be believed.
All three of these games represent Saturn gaming at it's finest. Trying to chose just one is like trying to decide which limb I don't need, because I need them all.
In the end Sega Rally gets my vote, not because I think it's better than any of the other games, or because a lot of other people have already picked it, but because it's the most accessible of the three games. Someone who knows nothing about gaming will probably pick it out of these three titles simply because the premise of a racing game is more familiar than the concept of the other two games, which I must admit are bizarre from the point of view of someone who's never played games. Of course, I did want to select PDZ because no-one else mentioned it, but it's ultimately not as accessible as Rally.
