I'm a huge Sega fan, but not because MK1 had fatalities in it. The Genesis was easily the worst Sega system.
Hrm...I always figured the Genesis to be the BEST Sega system since it got the most software support during the life cycle of ANY Sega console. The Saturn had a few games I loved (most notably, Dark Savior) and of course, the SMS with the original Phantasy Star is just plain classic, but the Genesis really, IMO, had the largest selection of titles I liked (the Sonic series, PSIV, a great Strider port, and even some oldies like Jewel Master and Columns). But again, it's all a matter of taste.
Well, if I owned stock in Sega in 1992, then I'd say I liked the Genesis the best because that's back when Sega actually made money. It was Sega's most popular machine in the US, therefore I can see the console warriors getting behind it. Its kind of like the WWII for patriots.
Even the worst Sega system is still a nice system, but I feel that it can't compare to the Saturn, or DC for many reasons.
From a hardware perspective, just chips and that sort of thing, the Mega Drive was weak sauce compared to its counterparts; the PCE, and the SuFami. As mentioned elsewhere on this forum the MD hardware didn't really excell at anything. It was resonably fast, so it did much better with shooters than the SuFami, but ultimatly the PCE is a better shooter system.
From a software perspective things are even worse. As we know, most software is crap so that leaves it up the small percentage of good stuff to define the machine. I really like Sonic 1, and 2, Phansaty Star IV, and Gunstar Heroes. I recently had a chance to get an X'Eye for a very good price, but I turned it down because I really don't know what I would play on it. Nobody wants to play garbage sports games from EA now that they are 10 years old, least of all me since I hate sports games. The same goes for movie licensed titles, or stuff based on toys and comic books. Anything that is multi-playform is almost always better on SNES (Ninja Turtles: Tournament Fighters, Street Fighter II, etc.
The Saturn gave us Guardian Heroes, Radient Silvergun, Sakura Wars, Bomberman SS, Fighters Megamix, VF2, Death Tank Zwei, great shooters...just amazing (Parodius, Salamander, DoDonpatchi, Batsugun, on and on and on), three Panzer Dragoon games, and a metric shitload of amazingly great ports of Capcom, and SNK fighters.
The DC gave us two more Sakura Wars games (part 3 is the best) more shooters, more fighters, Shenmue 2, Skies of Arcadia, Grandia 2, and Rez. Mother f*cking *REZ*, man.
I don't recall the MD doing anything like that. Not even close.
