Well, I didn't feel the need to name off a laundry list of titles that the SNES had as opposed to the Genesis, but I guess we will get down to it. It's not an age thing. The SNES simply is a better system. In most games the color even looks better. 8 bit sound quality is a big negative in my book. The controller complaints are just a matter of preference as well. I never liked the button design. There is a reason Sony copied the SNES with their controller. The Genesis did do some quality Arcade ports. No doubt about it. Altered Beast rocks.
There is no doubt that the Genesis had some solid titles that were just as good as the SNES ones. I suppose you can argue the 32X and Sega CD were decent peripherals, which I tend to agree, but the horrible design of the console and the hookups is unforgivable. It simply looks like shit. You can argue that you don't need to plug them all in, but the fact remains that they could have stuck with either the 32X OR the Sega CD so they didn't leave their early adopters high and dry. How many titles even took advantage of those two add ons? Not that many. The 32X was pointless imo. The SNES had simplicity as it's strength. Instead of adding some gaudy 32X type peripheral they threw in the FX chip on the cartridge with StarFox. As far as the Final Fantasy comment goes, you could substitute any number of other RPG's the SNES had that the Genesis didn't. The Genesis was lacking in that department aside from a few gems here and there. Shining Force is badass. No doubt about it.
Just a small list of titles aside from those already mentioned. I could give two shits about sports games. Genesis did have Joe Montana Football which was good.
Shadowrun - some prefer the Genesis version. The SNES version has a better story.
Super Punch Out - Genesis has nothing to compare to this.
F-Zero - I suppose Sega has Outrun.
Legend of Zelda: A Link to the Past - I can't think of a decent Genesis replacement for this.
TMNT: Turtles in Time
Terranigma
Super Bonk
Super Mario All Stars
Tecmo Super Bowl
Top Gear
Super Double Dragon
Super Adventure Island
The Legend of the Mystical Ninja
Super Bomberman
Secret of Mana
SimCity 2000
Illusion of Gaia
MegaMan X
Chrono Trigger
Dragon Quest
Killer Instinct - Eternal Champions is good. I would venture to say underrated.
Donkey Kong Country - Nothing on Genesis beats this as far as exclusive platformers go.
Super Metroid
Super R-Type
Lagoon - I just like this game.
Ogre Battle
Kirby
Yoshi's Island
I'll stop there. Most ports are better on the SNES. SNES has Genesis beat in RPG's and platforming. When people think back fondly to great JRPG's of yore they think Chrono Trigger and Final Fantasy 6. Whether that is good or not is irrelevant. Hardly anyone will mention Phantasy Star or Lunar. I would say they have them beat in fighting games too. I'm struggling to think of what Genesis has that is so much better than the SNES. Now if you bring up the Sega Saturn and Dreamcast then you can argue they had Nintendo beat in those generations, but the SNES is clearly superior in almost every aspect.
Or so it's said. Mega Drive games in general have way better soundtracks so what's that good for.
I just don't agree with you there pal. Final Fantasy 6 has an amazing soundtrack. I could name others. Name off some.
